Hi,
I'm new to this list, and I would be grateful if somebody could give me a hint. I'm trying to speed-optimize a completed and working SL design, and it appears as if an old topic is a main problem. This is the default XST option to merge a chain of FFs into a shift register. What I'm trying to accomplish is to run casper_xps with the right XST options from the start. What I have learned so far is that the XST options are written into the file system_xst.scr, which is re-generated before each run. The file fast_runtime.opt only applies to tools running after XST. Now I'm trying to figure out which tool is actually assembling this scr file, and where it gets the options from. In the hope that I can change the default behavior. Can somebody give me a pointer? Or is my approach fundamentally wrong? Thanks a lot Gunter from MPIfR Bonn
