Hello all -
I used the source rom.vhd at the bottom of:
formatting link
under Webpack ISE6.1 VHDL and was surprised that XST bombs on synthesis. FATAL_ERROR:Xst:Portability/export/Port_Main.h:127.1.13 - This application has discovered an exceptional condition from which it can not recover. Process will terminate. ...So I tried it in webpack ISE5.1; it synthesized and simulates fine. I tried re-installing ISE6.1 and related service packs, no change. What am I missing?
