I am wondering why question: Free VerilogA simulators was closed. Especially with reason "not constructive". It:
a) Has an answer that can be supported by facts, references, or specific expertise. Friendly: program XYZ with home page ABC support VerilogA will be OK as an answer.
b) I cannot see how such question will solicit debate, argument, or extended discussion.
The only reason I can see is "can solicit polling". But then all questions that have more than one correct answer should be closed. What will left is only stupid academic test question that by design have one correct answer.
Examples of similar questions:
Free RF Simulation Software
Generic free Verilog synthesis tools?
