dart_vcd

Description:

dart vcd

dart_vcd #
Reads and writes VCD (Value Change Dump) files, a common format used with logic analyzers, HDL simulators, and other EDA tools. It provides streaming wrappers to read and write VCD commands and data.

Port of rust-vcd to Dart.
Usage #
A simple usage example:
import 'package:dart_vcd/dart_vcd.dart';

void main() {
VCDWriter writer = StringBufferVCDWriter();

// Write header
writer.timescale(1, TimescaleUnit.us);
writer.addModule('top');
final clock = writer.addWire(1, 'clock');
final data = writer.addWire(1, 'data');
writer.upscope();
writer.enddefinitions();

// Write values
writer.begin(SimulationCommand.dumpvars);
writer.changeScalar(clock, Value.v0);
writer.changeScalar(data, Value.v0);
writer.end();

var t = 0;
for (var i = 0; i < 32; i++) {
t += 4;
writer.timestamp(t);
writer.changeScalar(clock, Value.v1);
writer.changeScalar(data, Value.v1);
}

print(writer.result);
}
