A professor is going to switch from Spartan 3 to Nexys 4 DDR. He comes up the following problem.
We’re still experiencing significantly longer synthesis/implementation times in ISE for Artix-7, compared to Spartan 3. I also tried the designs in Vivado, with similar results. This does depend a lot on the CPU in the computer running the software. My laptop (Intel Core i7) took 3:45 to do synthesis through place and route, whereas it took 9:26 in the lab and my desktop PC (Intel Core2 Quad Q8400). Add additional time for generating a configuration file. The Nexys4 sample project took over 13 minutes for implementation on my office PC.
If there are any project options that you know of that would shorten this time, we would love to try them out.
I have tried changing “Flow_RuntimeOptimize” to “Flow_Quick”, but for simple designs this only cut off a couple of seconds.
