Hello, I've finally started compiling some ROACH designs under 11.3. One thing that I noticed is that the PAR phase now reports both setup and hold timing metrics while routing. I also noticed hold times being critical paths in the timing reports now. I don't remember ever seeing anything like that in 7.1 (that is, hold times were never critical paths as I recall). Is something about the Virtex 5 architecture different that makes it more sensitive to hold times? Thanks, Glenn
