# The Beginnings of a high-performance, low memory footprint VCD Viewer in Rust for massive multi-GB waveforms
|
|
|
|
## Features
|
|
- very fast
|
|
- loads 200MB of VCD waveform per second on an 8 core 2017 desktop CPU with NVMe storage
|
|
- consumes roughly between 10 - 50MB of memory per GB of waveform
|
|
- elegant/pretty UI
|
|
- can be easily ported to work in browser via webassembly
|
|
- allows high-performance custom Rust plugins to manipulate and
|
|
generate new waveforms live
|
|
|
|
## Running
|
|
|
|
Make sure you have a test vcd file to get you started. You can grab
|
|
a large VCD file from
|
|
[here](https://drive.google.com/file/d/1pfm2qo2l8fGTHHJ8TLrg1vSGaV_TUbp2/view?usp=sharing).
|
|
|
|
The first build of the program may take some time.
|
|
|
|
``cargo run --release test-vcd-files/aldec/SPI_Write.vcd``
|
|
|
|
# TODO
|
|
- [x] We need a way to merge lines.
|
|
- [ ] Need to perform signal aliasing
|
|
- use vec of enum {Sig, Alias}
|
|
- [ ] Should insert nodes in BFS order
|
|
- [ ] Change states to lowercase
|
|
- [ ] We need to start regression testing the parser over all files
|
|
- [ ] Take a look at GTKWave parser to compare effificiency.
|
|
- [ ] Send survey to community channel.
|
|
|
|
### May 18
|
|
- [ ] move while loop into word yielding iterator
