I've got a really big design, and it takes a long time for asimut to compile, flatten, restore, link, etc. my design everytime I want to test some vectors.. I'm I missing something? Is there a way to save the design after asimut does all this work on it, and ask it to read that file everytime I want to only change the pattern file? Or is there another tool I don't know about?
