Hi, I would be grateful if you can help me with this error which I get after trying to run an EMX simulation on a PCELL.

I've found very limited information in this forum. Thanks

Hello,

I am trying to design an RF mixer for a TX.
Assume my input IF signal is at 1 GHz, my LO at 2 GHz and I want my RF at 3 GHz, and assume that the mixer fully works after testing it with HB.
How to simply set the envelope analysis to check the EVM ?
I read through the documentation but I couldn't get it (I couldn't fully understand the settings of the source, probe, analysis.)
Which source and probe to use? I want custom modulation with custom bandwidth and center frequency.
Is there some examples for the ENVLP analysis ?

I am using IC23.1 and spectre 20.1.354.

Hi,

In our design team, we're looking for a strategy to make all cell views self-contained. We are struggling to do so when nport devices are involved.

The nport file requires a full path, whereas what we need is a relative path to the current path of the cell in which we're using the nport.

I have browsed through the forums & cadence support pages, but could not find a solution.

1) There is a proposal from Andrew to add the file directory in ADE option "Simulation Files." :https://community.cadence.com/cadence_technology_forums/f/rf-design/27167/s-parameter-datafile-path-in-nport . This, however, is not suitable, because the cell is not self contained.

2) The new cadence version off DataSource "cellView" in nport options:

This however is not suitable for us due to two reasons:

i- Somehow we don't get this option in the nport cell (perhaps some custom modification from our PDK team)

ii- Even if we had this option, it requires to select the library, which again makes it unsuitable: We often copy design libraries for derivative products using "Hierarchical Copy" feature. And when the library is copied, the nport will still be pointing to the old library. Thus, it is still not self-contained.

In principle, it should not be difficult (technically) to point to a text file relative to the cell directory (f.ex we can make a folder under the same cell with name "sparFiles" & place all spar files under this folder), however it does not seem to be possible.

Could you perhaps recommend us a work-around to achieve our goal: making the cells which contain nport devices self-contained so that when we copy a cell, we do not have to update all the nport file destinations ?

Thanks in advance.

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

Socionext, a leader in SoC design, recently made significant strides in enhancing its design efficiency for a complex billion-gate project. Faced with the initial challenges of lengthy eight-day iterations and a protracted two-month timing signoff process, the objective was to reduce the iteration cycle to just three days. By integrating Cadence's cutting-edge solutions—Certus Closure Solution, Tempus Timing Solution, and Quantus Extraction Solution—Socionext achieved remarkable improvements.

Notably, the Tempus DSTA tool dramatically cut timing closure time by 73%, outperforming conventional single-machine STA methods. This achievement, combined with the synergistic use of Cadence's Certus Closure and Tempus Timing solutions, allowed Socionext to meet their ambitious three-day iteration target and double productivity. Additionally, integrating these solutions significantly decreased both human and machine resource needs, slashing memory and disk costs by up to 90% and halving engineering resources during the optimization and signoff phases.

For more on this collaboration, check out the "Designed with Cadence" success story video on Cadence's website and YouTube channel.

Also, don't miss the on-demand webinar "Fast, Accurate STA for Large-Scale Design Challenges," which provides a deeper dive into Socionext's breakthroughs and the innovative solutions that powered their success.

The traditional methods of power analysis lag by various shortcomings and challenges:

• Getting an accurate measure of RTL power consumption during design exploration
• Getting consistent power through the design progress from RTL to P&R.
• System-level verification tools are disconnected from the implementation tools that translate RTL to gates and wires.

The Cadence Joules RTL Power Solution closes this gap by delivering time-based RTL power analysis with system-level runtimes, capacity, and high-quality estimates of gates and wires based on production implementation technology. The Cadence Joules RTL Power Solution is an RTL power analysis tool that provides a unified engine to compute gate netlist power and estimate RTL power. The Joules solution delivers 20X faster time-based RTL power analysis and can analyze multi-million instance designs overnight, with impressive accuracy within 15% of signoff power.

Moreover, it integrates seamlessly with numerous Cadence platforms, eliminating compatibility and correlation issues! In addition, the Joules RTL Power Solution GUI (Graphical User Interface) helps you analyze/debug the power estimation/results using several GUI capabilities.

Want to take a tour of this power estimation world? Gear up to attend the training class created just for you to dive deep into the entire flow and explore this exciting power estimation method/flow with hands-on labs in two days!

In an era of abundant and constantly evolving information, the challenge is not just accessing knowledge but understanding and applying it effectively. AI is a transformative technology that is reshaping how we learn, work, and grow. In this blog, we’ll explore how AI accelerates our knowledge acquisition and understand how it can relate to the process of learning, which connects with our daily lives.

The role of AI is to accelerate knowledge by personalizing learning experiences, providing instant access to information, and offering data-driven insights. AI empowers us to learn more efficiently and effectively in many ways. I won't go into much detail, as we are already busy searching for the meaning of AI and what it can do; however, I want to share one inspiring fact about AI. It can analyze vast amounts of data in seconds, making sense of complex information and providing instantaneous actionable insights or concise answers. I understand that humans are looking to speed up things, which can help us understand technology better and perform our tasks faster.

The main reason AI is in focus is because of its ability to perform tasks faster than ever. We aim to enhance the performance of all our products, including the everyday household electronic items we use. Similarly, are we striving to accelerate the learning process? I am committed to assisting you, and one such method is concise, short (minute-long) videos.

In today's fast-paced world, where attention spans are shorter than ever, the rise of social media platforms has made it easier for anyone to create and share short videos. This is where minute videos come in. These bite-sized clips offer a quick and engaging way to deliver information to the audience with a significant impact. Understanding the definitions of technical terms in VLSI Design can often be accomplished in just a minute.

Below are the definitions of the essential stages in the RTL2GDSII Flow. For further reference, these definitions are also accessible on YouTube.
