基于 llparse 的 vcd 解析器,用于 Digital IDE 的 wave 渲染器 的 vcd 后端解析器构建。
git clone https://github.com/Digital-EDA/digital-vcd-parser
cd digital-vcd-parser
npm i
npm install browserify terser node-gyp -g
# 激活 emcc
source $EMCC_HOME/emsdk_env.sh
# 生成 vcd_parser.c 和 vcd_parser.h(每次修改 ./bin/build.js 都需要重新运行)
# llparse 使用教程:https://kirigaya.cn/blog/article?seq=223
node bin/build.js
# build
make -j 12
生成 :
./out/vcd.js
./out/vcd.wasm
部署到 digital-vcd-render :
# 将生成的 wasm 通过 浏览器化和特殊处理后部署到 render 项目中
source deploy.sh /mnt/c/Users/11934/Project/Digital-IDE/digital-vcd-render
快速测试:
node test/debug/basic.js
通用测试:
npm run test
tip: 不要运行
browserify
如果你要进行测试的话
source deploy.sh /path/to/digital-vcd-render
Only stream of Uint8 is supported as input. e.g. we want to parse a certain *.vcd
read in browser-like environment. Mount vcd to window in your index.html
:
<!DOCTYPE html>

In your main workspace (App.vue
for example), goes like this:
const uint8array = await readVcdFile();
const vcdstream = await getVcdStream();
// level size diagram data
const values = {};
vcdstream.change.any((id, time, cmd, value, mask) => {
if (values[id] === undefined) {
values[id] = [];
}
values[id].push({time, cmd, value, mask});
})
const maxChunkLength = 1 << 17;
for (let i = 0; i < uint8array.length; i += maxChunkLength) {
const piece = uint8array.slice(i, i + maxChunkLength);
vcdstream.write(piece);
}
// structure info of wires in vcdstream.info
console.log(vcdstream.info);
