MAX+plus II 8.0

Ok, first off, I know that version 8.0 of MAX+plus II, from 1997, is old, obsolete, etc. However, I'm desperately trying to recreate a build of some old VHDL code in an attempt to reproduce a binary ...

Some FPGA tools use random numbers to make routing decisions. If this is the case with your MAX+ tool, you won't be able to reproduce the build without the random number seed used to create the build.

This is true of all fit engines, they are fed a seed value to get different fit results. But this seed is based on source-code and manual seed value. Given the same tool version on the same platform with the same source code and same fit seed, you should get identical results (and this is a very important thing).
