I have recently had lots of incorrectly synthesised logic with the synthesiser I am using. My latest design occupied approx 20% of a "6 million gate" FPGA, and had a total of 5 incorrectly synthesised parts (which took some finding).
Can anyone recommend any synthesisers which do not suffer from this sort of problem?
The synth takes approx 1 hour to synth this (much quicker than most of my "large" designs), and timing far exceeds the requirements as the clock frequency is low.
If anyone is interested, the sort of errors I was getting were:-
A connection between 2 components was simply not made. An input to the second component was hardwired to '0'. Tried the very latest version of the same synth and the problem went away.
The following problems were seen in the latest version:-
