feature request: Logic Element Estimator #58

Closed TChapman500 closed 4 years ago

TChapman500 commented 4 years ago

Add something that gives an estimate on how many FPGA logic elements will be used by a given circuit. For example: "FPGA -> Logic Block Estimate".

Great idea! But is this even feasible? Logisim already has a built-in stats/reporting tool that will show you some simple statistics about your design (number of circuit elements -- gates, etc., -- broken down by type, etc.) But for an FPGA, "logic elements" is a complex and fuzzy concept. It would likely depend on vendor, device, etc., and fairly complex rules. It would probably also depend on the pin I/O resource assignments. Can this can be farmed out to an external tool?

Good points.

Closing as wontfix for now. Will re-open if new ideas come up.
