You begin writing some UVM code and there are parts of the code that aren’t done yet, so you begin to use uvm_objection, guarding that code. Rich Edelman, a product engineer at Siemens doing verification debug and analysis, wrote a paper on this topic, which I just read. This blog covers the topic of objections and provides some different… Read More

I just read an interesting white paper on functional verification of analog blocks using SV-RNM (SystemVerilog real number modeling). The content is worth the effort to read closely as it elaborates a functional verification flow for RNM matching expectations for digital logic verification, from randomization to functional… Read More

PSS at #61DAC min

Accellera invited me to attend their #61DAC panel discussion about the new Portable Stimulus Standard (PSS) v3.0, and the formal press release was also just announced. The big idea with PSS is to enable seamless reuse of stimulus across simulation, emulation and post-silicon debug and prototyping.

Transistor-level circuit designers have long used SPICE for circuit simulation, mostly because it is silicon accurate and helps them to predict the function, timing, power, waveforms, slopes and delays in a cell before fabrication. RTL designers use digital simulators that have a huge capacity but are lacking analog modeling.… Read More

Making UVM faster through a new configuration system

Making UVM faster through a new configuration system
by Daniel Payne on 12-26-2023 at 10:00 am

Elapsed Time min

The Universal Verification Methodology (UVM) is a popular way to help verify SystemVerilog designs, and it includes a configuration system that unfortunately has some speed and usage issues. Rich Edelman from Siemens EDA wrote a detailed 20-page paper on the topic of how to avoid these issues, and I’ve gone through it to… Read More


Bespoke Silicon Requires Bespoke EDA

Bespoke Silicon Requires Bespoke EDA
by Michiel Ligthart on 10-26-2022 at 10:00 am

Bespoke EDA

When I first heard the term ‘bespoke silicon,’ I had to get my dictionary out. Well versed in the silicon domain, I did not know what bespoke meant. It turns out to be a rather old-fashioned term for tailor made and seems to be very much British English. The word dates from 1583 and is the past participle of bespeak, according… Read More


Connecting SystemC to SystemVerilog

Connecting SystemC to SystemVerilog

UVM Connect

Siemens EDA is clearly on a mission to help verifiers get more out of their tools and methodologies. Recently they published a white paper on UVM polymorphism. Now they have followed with a paper on using UVM Connect, re-introducing how to connect between SystemC and SystemVerilog. I’m often mystified by seemingly overlapping… Read More
