Allegro part of DPI does not support scaling above 150%

Hi All

I followed tutorial video below for using Design link

https://www.youtube.com/watch?v=f9JmFF8lqA0

and I followed the video with embedded board design file which should be same one on video

I did every set. but  at 2:55 of video, Steve have the tabs of both design names on top of Constraint Manager in video

but my one didn't exist them

which one would be different?

there was some comment on command windows but I think they would not be problem here

Hello. I am using Cadence 17.4 tools. When I open a package symbol (.dra) or board file (.brd) in Allegro that was created in an older version of the tool I get a message like this one (as expected):

"The design created using release 17.2 will be updated for compatibility with the current software..."

If I create a symbol or board file from scratch in the 17.4 tool then open it later, I get the same message. (always referring to version 17.2 which is the previous version I was using here).

So far this has not caused me any problems, but I would like to understand why it is doing this in case I have something setup incorrectly.

I only have version 17.4 installed. I am not exporting to a downrev version when I save (i.e. not using File->Export->Downrev design…) and in User Preferences->Drawing I don’t have anything selected for database_compatibility_mode. What else might I check?

FYI here is the tool version information that I see after selecting Help->About Symbol:

OrCAD PCB Designer Standard 17.4-2019 S012 [10/26/2020] Windows SPB 64-bit Edition

Thanks -Jason

I need to add a new CDF parameter called "mag" to symbols in a given library using skill script in which the symbol size can be controlled and call back it each time this library is used so that all the symbols are updated.

Hello,

I have a question about toggle coverage.

In my case, there are many unused registers or wires that are affecting the toggle coverage score negatively.

Is it possible to automatically exclude registers or wires that are not used from toggle coverage?

My RTL code is as follows, Is it possible to automatically disable tb.top1.b and tb.top1.c without using an exclude file?

module top1;

  reg a;

  reg b;

  reg [31:0] c;

  initial

  begin

  #1 a=1'b0;

  #1 a=1'b1;

  #1 a=1'b0;

  end

endmodule

module tb;

  top1 top1();

endmodule

Hi

the signal SPI_SCLK belongs to TWO Spacing CLASSES: CLS_SP_SPI and CLS_SP_SPI_CLOCK

I then assign TWO different SPACING RULES to each class : CLS_SP_SPI  > 2H and CLS_SP_SPI_CLOCK > 3.5H

Which SPACING RULE will inherit the signal SPI_SCLK ??

Is it possible to manually define the PRIORITY on Design Rules ??

Hi

I have fixed a SPACING RULE (SP1) for a CLASS_DIFF_PAIR whereas for via associated to the net (DP_VIA), the DISTANCE > 60mils respect to ANY other vias (PTH, BB, TEST vias)

Now my problem is that this rules should NOT be applied for GND VIAS (STICHING VIA) which must be placed at a distance < 40mils respect to DP_VIA

How to create an exemption to the SPACING RULE (SP1)?

Hello everyone!

Have you ever used the axlDllOpen function for Allegro 16.6?

It doesn't work for me. Please give me your solution.
Thank you.

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?

Regards,

Rohit Rohan

Has anyone experienced the same situation?

The world of electronics design thrives on efficient tools that bridge the gap between concept and silicon. Virtuoso Digital Implementation is a powerful ally for mixed-signal designs, which integrate both analog and digital components. This blog post will examine Virtuoso Digital Implementation's capabilities and explore how it can streamline your mixed-signal design workflow.

Virtuoso Digital Implementation in a Nutshell

Virtuoso Digital Implementation is a license package within the Cadence Virtuoso Design Platform. It offers a streamlined RTL-to-GDSII flow to implement smaller digital blocks within a mixed-signal design environment. Here's what makes Virtuoso Digital Implementation stand out:

• Focus on Small Digital Blocks: Optimized for digital blocks with an instance count of up to 50,000 (expandable to 150,000 with specific configurations), Virtuoso Digital Implementation is ideal for integrating digital logic into your analog-centric design.
• Leveraging Industry Leaders: Virtuoso Digital Implementation utilizes cut-down versions of the renowned Cadence Genus Synthesis Solution and Innovus Implementation System under the hood. This ensures you get access to proven technologies for logic optimization and place-and-route.
• Seamless Integration with the Virtuoso Environment: Virtuoso Digital Implementation's key advantage is its tight integration with the Virtuoso Layout Suite. You can launch the synthesis and place-and-route tools directly from the Virtuoso environment, eliminating the need to switch between platforms.

Benefits of Using Virtuoso Digital Implementation

 By incorporating Virtuoso Digital Implementation into your mixed-signal design flow, you can get several benefits:

• Simplified Workflow: Virtuoso Digital Implementation offers a centralized environment for both digital block implementation and layout editing within the Virtuoso environment. This reduces context switching and streamlines the design process.
• Faster Time-to-Market: Virtuoso Digital Implementation's streamlined workflow can significantly reduce design turnaround times, allowing you to get your product to market quicker.
• Improved Design Quality: Leveraging industry-leading synthesis and place-and-route engines from Cadence ensures high-quality digital block implementation within your mixed-signal design.

Who Should Consider Virtuoso Digital Implementation?

 Virtuoso Digital Implementation is a valuable tool for anyone working on mixed-signal designs with smaller digital blocks. It's particularly well-suited for:

• Analog IC designers who need to integrate digital logic into their designs.
• Circuit design teams working on mixed-signal applications like data converters, power management ICs, and RF transceivers.

Virtuoso Digital Implementation provides a compelling solution for designers working on mixed-signal projects. Its streamlined workflow, tight integration with the Virtuoso design platform, and access to proven digital design tools can significantly improve design efficiency and time-to-market. Virtuoso Digital Implementation is worth considering if you're looking to optimize your mixed-signal design flow.

A more appropriate title for this blog could be “All Vehicles with ADAS Need the Midas Functional Safety Platform”.

EVs tend to have advanced driving assistance systems (ADAS) because they’re newer, but not all vehicles with ADAS are EVs!

Certifying Advanced Driver Assistance Systems (ADAS) is a multifaceted process involving rigorous testing, validation, and regulatory compliance to ensure safety and reliability.
As ADAS technologies become increasingly sophisticated, the certification process is evolving to meet these challenges.

The ISO26262 standard provides the requirements to be met to attain safety certification for digital designs.

One of the key aspects of ADAS certification is functional safety. This includes:

• Ensuring the system operates as intended under all conditions, including failures.
• Adherence to standards like ISO26262.
• Rigorous testing to identify potential hazards and mitigate risks.

The Midas Safety Platform provides early-phase exploration of functional safety architectures and leverages native chip design data to perform accurate safety analysis efficiently.

The platform is a unified solution available across Cadence products, and with its modular architecture, it supports both embedded and standalone usage with the Cadence flow.

After extracting the design information, an output Midas database file contains the isolated DUT and provides the design components and their fault tolerances to various tools in the flow.

Conformal can easily verify design transformations that include necessary components like TMR for safety.

In these videos, we explore how to create reports for both Transient and Permanent faults.
