Just to clarify here - I didn't mean that the actual gate switching=20 speeds will drop as the complexity increases, rather that the timing=20 constraints become tighter when the design becomes more complex and path=20 delays increase (so you have to drop the clock speed) --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
