I have a set of old FPGA files. I'm trying to identify the tool that created them so I can try to import them into a current tool.
The file extensions of the set of files are *.abl, *.pin, *.ipf, *.dri and others.
The files are 10-15 years old. They were originally built on a Sun Workstation.
The target package is an Actel A1280A.
