Release Notes for Icarus Verilog Snapshot 20021019 The synthesizer now detects asynchronous set/reset inputs to DFF devices. The fpga and vvp code generators have been updated to support these signals. The vvp code generator also gained some register management code that improves the thread register usage. This redoces code size for certain common cases, and thus improves simulation performance. The requirements on `ifdef and related compiler directives has been relaxed, to correspond to more common behavior. The parameter range support crashed if the range expressions had parameters in them. This is fixed, and some signed-ness bugs fixed along with it. Rearrange some of the configure script tests to assure better compatibility accross platforms. |
