Hi all,

I have been following the tutorial "Innovus Block Implementation with Stylus Common UI", version 23.1.

While I was doing the clock tree synthesis, the tutorial calls for a command

clock_opt_design

But my tool tells me this is a beta feature which needs to be enabled.

Warning: clock_opt_design requires beta feature innovusClockOptFlow enabled.

Can I ask how do I enable this beta feature?

My version of Innovus is v21.35-s114_1, is it because of the version incompatibility?

Many thanks

Hi,

I hope you are doing well.

I have designed and simulated a PA system in Cadence using high-level blocks, which include both ideal components and some defined with Verilog-A. My goal is to calculate the Bit Error Rate (BER) and Error Vector Magnitude (EVM) in the system. I am using an LTE source from RFLib, and everything functions correctly in the transient simulation.

To calculate these parameters, I intended to use envelope simulation. However, when I attempt to run the envelope simulation, I encounter convergence errors, which prevent it from working as expected.

Given this issue, I believe I need to work with transient data instead. Could you please advise on how to approach this in Cadence without exporting the data to MATLAB?

Thank you for your assistance.

Hi there

I am trying to make cross-probe btw layout and schematic view.

so when I execute the code in schematic using bindkey, the code will raise the layout view (hiRaiseWindow)

and then I want to descend to the same hierarchy as schematic. (geSelectFig, leHiEditInPlace)

But looks like current cellview still stays at schematic view.

I got this error msg, and when I print current cell view name at where I got this msg, it replys schematic.

*Error* geSelectFig: argument #1 should be a database object (type template = "d") - nil

is there any way to change the current cellview to layout view?

I also added this code, but didn't work.

geGetEditCellView(geGetCellViewWindow(cvId)) ;cvId is layout view

I don't want to close the schematic view, just want to move the focus or make geSelectFig works.

Thanks in advance.

Explore Impacts of Finite Interconnect Impedance on PDN Characterization

Over the past few decades, many details have been worked out in the power distribution network (PDN) in the frequency and time domains. We have simulation tools that can analyze the physical structure from DC to very high frequencies, including spatial variations of the behavior. We also have frequency- and time-domain test methods to measure the steady-state and transient behavior of the built-up systems.

All of these pieces in our current toolbox have their own assumptions, limitations, and artifacts, and they constantly raise the challenging question that designers need to answer: How to select the design process, simulation, measurement tools, and processes so that we get reasonable answers within a reasonable time frame with a reasonable budget.

Read this award-winning DesignCon 2024 paper titled “Impact of Finite Interconnect Impedance Including Spatial and Domain Comparison of PDN Characterization.” Led by Samtec’s Istvan Novak and written with a team of nine authors from Cadence, Amazon, and Samtec, the paper discusses a series of continually evolving challenges with PDN requirements for cutting-edge designs.

Hello Fellow PCB Designers,

We have a 10 layer PCB design that originated in Pads and was converted over to Allegro 17.4, this is an old design but is manufacturable and works perfectly fine.  When I try to generate a Gerber for the Top or Bottom layers

the Gerber comes out fine.  But Most of the middle layers are Etch's and via's for power and grounds, but the Gerber's come mostly blank, there might be some details, but in the Gerber view everything is displayed correctly.

The design does have many close spacings, I have not changed anything in the constrains manager yet, turned off a lot of the DRC's, but thinking there might be something wrong with the constrains.

  I find that the CSet is set to 2_18, not sure yet what this means, also there are many of these definitions, PCS 3,4,5,ect, are the same as CSet 2_18 any suggestions would be great, we are currently looking into this, have seen

that even small change in constraint manager can cause long processing and even Allegro crashing, this is a large project.

Thanks Much, Thanks, Mike Pollock.

Hello,
I'm trying to characterize a full adder that use transmission gate.
Unfortunately, the power calculation are wrong for the cell are always negative.
Is there any method or commands that can can help in power calculation or add the power consumption by the input pins to the power calculation ?
Another question, Is liberate support the characterization or transmission gate cells as standard cells or I should use liberate AMS for these type of cells ?
Thanks in advance,

Hello everyone,

I hope you're all doing well. I’ve set up two testbenches (TB1 and TB2) for my Design Under Test (DUT) using Cadence IC6.1.8-64b.500.21 tools, as shown in the attached figure. The DUT has multiple views available: schematic, Calibre, Maestro, and Symbol, and each testbench uses the same DUT in different scenarios. Currently, I have to manually switch between these views, but I would like to streamline this process.

My goal is to use a single config view that allows me to switch between the schematic and the extracted (Calibre) views. Ideally, I would like to have a configuration file where making changes once would update both testbenches (TB1 and TB2) automatically. In other words, when I modify one config, both testbenches should reflect this update for a single simulation run.

I would really appreciate it if you could guide me on the following:

1. How to create a config view for my DUT that can be used to easily switch between the schematic and extracted views, impacting both TB1 and TB2.
2. Where to specify view priorities or other settings to control which view is used during simulation.
3. Best practices for using a config file in this scenario, so that it ensures consistency across multiple testbenches.

Please refer to the attached figure to get a better understanding of the setup I’m using, where both TB1 and TB2 include the same DUT with multiple available views.

Thank you so much for your time and assistance!

I'm working on the code coverage. Doing a metrics analysis by default we see overall average grade and overall covered. But when i do a block analysis on an instance i see overall covered grade, code covered grade, block covered grade, statement covered grade, expression covered grade, toggle covered grade.

As I dont know the difference I started to read the IMC user guide and came to know there are 3 things we come across while doing a code coverage local, covered, average

From my understanding

local - child instances metrics doesnt reach the parent level. For example, we have an instance Q and its sub instances like Q.a, Q.b. Block Local grade of Q can be 100% even when its instances Q.a and Q.b a block local grades isnt at 100%.

In the attached image there is formula 

The key difference between average and covered is the weights.

Average : Mathematically taking the above scenario where Q.a, and Q.b has 10 blocks each. Q.a has covered 8 blocks and q.b has covered 2 blocks. Now if we take the normal average it should be total covered/ totatl number = 8+2/10+10 yielding 50%. But when we add weights saying Q.a is 70% and Q.b is 30% the new number would be (8*0.7+2*0.3) / (10*0.7+10*0.3) resulting 62%. Because of the weights we see 12% bump.

Covered: there is no role of weights.

Among these 3 metrics i've changed my default view to this in the image to get more realistic picture when i do analyze metrics. Do you guys agree with the approach?

Hi

I'm learning Hb analysis for the IIP3 simulation of a gilbert mixer. My f_RF=5GHz, f_LO=4GHz and f_IF=1GHz . I'm a bit confused about setting the 1st order and 3rd order harmonic at the Direct plot form. I have set 1st order harmonic = 1GHz and 3rd order harminic = 2*f_LO-f_RF = 3GHz and it gives me the following results.

This is my 1dB compression point result

Hb analysis window

Direct plot window

Please let me know if my harmonic selection is correct and whether I'm getting a correct IIP3 and P1db curve

The default behaviour of Place replicate update is to select every new net item connected to the replicate module. This leads to an abundant number of clines, vias and shapes being selected, most of which I don't want to add to the replicate group. It is very tedious to unselect all these items and more often than not, I miss one or two items and then end up with a via or cline in a completely different place on the board or outside of the board.

Is there a way to change this rather annoying behaviour? I haven't found any way to disable it or to batch deselect everything the tool has decided to add to the replicate group.

The question has been asked before, but it didn't get any answers and the thread is now locked.

Hai Community,

What are the differences between the Cadence OrCAD / Allegro 24.1 with the Altium Designer 24.

Can I get the grid matrix difference between these two tools?

The Cadence Cerebrus Intelligent Chip Explorer is a revolutionary, machine learning-driven, automated approach to chip design flow optimization. Block engineers specify the design goals, and Cadence Cerebrus will intelligently optimize the Cadence digital full flow to meet the power, performance, and area (PPA) goals in a completely automated way. Use Cerebrus Apps to optimize some aspects of the design as well.

Running a full RTL to GDSII flow, Cadence Cerebrus has a lot of possibilities and combinations of different tool settings to explore.

Using the knowledge from previous runs, combined with on-the-fly analysis within the flow, Cadence Cerebrus can assess many settings combinations and fine-tune the flow accordingly in a very efficient manner.

As technology advances, projects become bigger and way more complex than before. The ability of a single engineer to run simultaneously a large number of blocks in a traditional way is limited. Cadence Cerebrus allows a single engineer to work more efficiently and implement more blocks, while maintaining the same or even better PPA, using compute power.

Being such a revolutionary tool, integrating Cerebrus into your existing flow is surprisingly simple as it can wrap around any existing flow scripts.

Please join me in this course, to learn about the features and basics of Cadence Cerebrus Intelligent Chip Explorer.

We’ll walk through the tool setting stage, explain what is a primitive and how it effects our run, talk about the cost function and the run goals.

We’ll understand the concept of scenarios, learn how to analyze the results of the different runs, and compare them.

In addition, we’ll talk about basic debug rules and methods to analyze failures.

Sounds Interesting?
