説明

When I generate HDL from a state diagram, StateCAD seems to hang. In this case, StateCAD is stuck in the first checking or compile stage.

ソリューション

During the compile stage, the minimization algorithm can appear to hang on "transition" (which uses a lot of product terms). This might happen when the design contains comparisons (e.g., ==, >=, etc.) or other equations that produce a large number of min terms.

Turning off minimization and indeterminate transition checking will solve this problem.

To turn off these two options:

1. Go to Options -> Configuration.

2. Uncheck the respective boxes ("Minimize" and "Indeterminate Transitions").
