added caching mechanism #492

Open yonnorc42 opened 1 week ago

For the larger designs like jpegencode, a lot of the runtime is spent initializing the list of possible matches for each primitive based on cell type and properties. This pr creates a caching mechanism which rebuilds the dict based on the instance names. For jpegencode, this brought the runtime down by 29 minutes.

The caching messes up error injection because normally error injection will catch flipped bits during the initialization of the possible matches.
