Verijit – Up to 100x faster Verilog simulation

YouTube

Hi! We build fast verilog simulators using just in time compilation. Our simulator outperforms existing verilog simulators by up to x100. verijit is a project by @cfbolz and @CanLehmann.

Check out out demo video here: https://www.youtube.com/watch?v=PXgUsEjvAOY

Verijit – Up to 100x faster Verilog simulation

YouTube

I can finally talk about what I did during the last year! In collaboration with @cfbolz we developed a Verilog simulator called verijit based on meta-tracing just in time compilers. The results are pretty crazy: verijit is up to 100x faster than verilator for simulating processors.

You can follow us on Mastodon @verijit

We have a neat mandelbrot demo below:

🌘 VHDL 的核心瑰寶:論其如何維護確定性
➤ 從 Delta Cycle 看 VHDL 與 Verilog 的本質區別

本文深入剖析了硬體描述語言(HDL)中一個關鍵的設計哲學差異。作者將 VHDL 的「Delta Cycle」(增量週期)演算法譽為該語言的皇冠明珠,並解釋了為何該機制能確保模擬結果的確定性。相較之下,Verilog 因缺乏類似的嚴格分階段處理機制,導致在處理併發事件時容易出現非確定性的結果。作者認為,VHDL 通過將信號更新與流程評估強制分離,以極低的成本解決了併發設計中的核心問題。
+ 這篇文章精準地擊中了 Verilog 使用者的痛點。非阻塞賦值的確經常被誤用,而 VHDL 的這種嚴謹性確實讓大型複雜系統的模擬更具可靠性。
+ 很喜歡這種深入底層邏輯的分析。雖然現在 EDA 工具越來越強大,但理解 Delta Cycle 對於除錯模擬中的奇異現象(race conditions)仍然至

VHDL's crown jewel

How VHDL preserves determinism In this post, I would like to talk about VHDL’s crown jewel: how it preserves determinism in a concurrent language. Here is a figure of how it works:

Adding an enable signal to 🏝️ Isle.Computer drawing engine was more of a pain than I expected, but we're now ready to share vram access with the CPU. On the plus side, this also allows you to slow the action down so you can see the drawing happen. #FPGA #verilog

Fun in the frequency domain 🤓 Camera pointed at it's own display also showing audio FFT for cool glitchy visualizer effect. Video processing all done in PipelineC hardware. And how?
