vcd2vcd tool

vcd2vcd the tool to filter: * only needed signals * only specific time range * processing based on specific filter function

more efficient trigger lookup

1

Implement a more efficient way of looking up expected triggers. Maybe https://en.wikipedia.org/wiki/Trie ?

[WASM] fast way of converting to BigInt

1

Find a faster way of transferring bigInt from WASM to JS. https://github.com/wavedrom/vcd/blob/6ae6413d0fd2ed066a6fc4a5bb9385fcea8eaa65/lib/wrapper.js#L13

Construct a new format while parsing the VCD file. https://github.com/wavedrom/inspect/issues/1

compact form for bit vector literals

1

Verilog allows bit vectors or arbitrary width. Example `wire [26:0] state` VCD dump state changes like `b101010101010101010101010101` We need a compact binary form of storing such constants. ### LEB128 option...

Write generator for constraint random VCD file with specific properties: * Number of signals * Total simulation cycles * Change density * Random seed JS script? C/C++ generator?
