A High performance, VCD Parser written in Rust
x/z value parsing currently fails in cargo test.
A fix is coming.
Current Features
- pretty fast, parses 3.04 GB VCD file in ~62s on M1 Macbook Air.
Current Limitations
Unable to handle VCD files that have signals with more than 2^32 - 1 = 4,294,967,295 deltas/changes.
Running
This repository comes with several smaller VCD files emitted from various EDA tools. If you want a larger VCD file, grab one from here.
The first build of the program may take some time.
cargo run --release test-vcd-files/aldec/SPI_Write.vcd
You can run all the tests with cargo test
TODO
Features
- handle signals with x or z as string - the one bit parsers may also need to handle string
- move parse_orphaned_vars to scopes.rs
- Print out git commit or release number.
- Should be able to load waveform whilst viewing it live. - could be quite challenging to implement for various reasons
- Take a look at GTKWave parser to compare efficiency.
- re-order all signal timelines as binary balanced trees with respect to timestamps - support multithreaded re-ordering
Repairs
- make a custom date parser for possibly up to 18 different versions(that is, for each possible tool).
- Consolidate error messages and add cursors throughout.
- Fix warnings especially usage and restriction warnings once I'm able to successfully parse all sample VCDs.
Code Consistency
- Change error messages to line and filenames. Go through all calls to
format!whilst also keeping performance in mind.
Marketing
- Send survey to community channel.
