Logisim Evolution

[djsb]

Just thought I'd share my discovery of this open source logic simulation software. It's a further development of the original Logisim.

There is a short video here that first made me aware of this software.



There are a few more on YouTube.

This is interesting. Especially since it supports VHDL. It could be a useful tool to create quick testbenches to test pieces of VHDL code. I might give this a try; I have an upcoming VHDL project.

My test benches use bus-functional models of the devices that connect to the FPGA design. I don't know how well that would work in this environment.

I'm a little leery of installing this on Windows. Unsure about the other versions and OS's, but some rather unusual things appear to be going on in the latest v3.4.5 for Windows:

Hopefully someone can come along with evidence that this behavior is truly benign.

Right, I think the code itself is fine. Just some peculiarities about the installer are triggering suspicion.

• Why is msiexec.exe started in 'C:\Users\admin\Downloads\msiexec.exe'?
• Why are files written to 'C:\Windows\ServiceProfiles\LocalService\AppData\Roaming\Microsoft\UPnP Device Host\upnphost\udhisapi.dll' and 'C:\Windows\System32\Tasks\Microsoft\Windows\DiskDiagnostic\Microsoft-Windows-DiskDiagnosticDataCollector'?
• Why is the registry key 'HKLM\SOFTWARE\Microsoft\Windows Media Player NSS\3.0\Servers\A70D59A1-8EAD-4F40-AAAB-FBFC460800A4\FriendlyName' set to 'WORK:admin'?

In any case, I was able to extract the .msi using https://www.legroom.net/software/uniextract#download (7zip would not work) and THAT all tests fine, nothing suspicious.  Runs fine, too.  It does cause a Windows Firewall message to popup, asking for access to your network/domain.  Can un-check and click Cancel.
