WinCUPL & Microchip SPLDs and CPLDs - A new release for Win10/Win11

[Mark Durham]

Thought I would post this in case it's of interest to others.

Today I was looking for the WinCUPL install files on the Microchip website so I could try WinCUPL via WINE on Linux whilst I tinker with an ATF1504 device.

On the WinCUPL download page, I noticed mention of WinCUPL II. The download says that it is version 1.0.0 Beta and dated August 6th, 2025. The revision history says that it is a "New version with new GUI for Windows 10/11 support."

I've not installed it yet - life getting in the way and all - but it might offer a better experience than the original WinCUPL.

Mark.

Yes, WinCUPL II is definitely a better and less temperamental programme, but it should be noted that this package does not have a working simulator.

I saw it yesterday. Downloaded and installed it on Ubuntu under Wine. Everything seems to be working.

Oh wow, I definitely missed this release.

I installed it and had a very quick poke around. The interface is very fresh compared to the old WinCUPL, but functionality seems quite limited (e.g. there's no waveform editor for the simulator, if that works at all as suggested by Tadeusz), not too much more than a text editor.

I hope they will continue to develop it and add new features. But it has been about 6 months now with no further releases seemingly, so who knows, maybe this will be it (or it'll just be a slow release schedule).

I just checked again today and WinCUPL II is now at v1.1.0 released on 28th Feb 2026 with bug fixes, new examples and an updated help file. Nothing mentioned about the simulation side. Hopefully I will have time to play with it this week as I am using an ATF1502/4 in my next project.

Anybody try the windows version?

As far as I know, the only release is for Windows. I've recently switched to Linux so am running the latest version via wine. I also have WinXP running on a virtual machine and the old WinCUPL just to visualise the simulation output.

I'm a beginner with WinCUPL and CPLDs so can't offer much of an opinion on the latest updates. I don't know if Microchip will release an updated GUI for the simulation. If they don't, then I might try a python script to convert the simulation output file into a format that Sigrok pulse view can import. It won't be perfect but it might be good enough for simple logic.
