A High performance, VCD Parser written in Rust
Current Features
- pretty fast
Planned Features
- rapid log2n scrubbing through a signal's timeline
Current Limitations
Unable to handle VCD files that have signals with more than 2^32 - 1 = 4,294,967,295 deltas/changes.
Running
Make sure you have a test vcd file to get you started. You can grab a large VCD file 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
-
make a custon date parser for possibly up to 18 different versions(that is, for each possible tool).
-
Fix warning especially usage and restriction warnings once I'm able to successfully parse all sample VCDs.
-
Change error messages to line and filenames. Go through all calls to
format!whilst also keep performance in mind. -
Create compressed fungible numeric enums with good heuristic support.
-
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
-
Consolidate error messages and add cursors throughout.
-
Consider what to do with don't care values will probably just convert them to strings for now.
-
Include line and possible column numbers
-
Take a look at GTKWave parser to compare effificiency.
-
Send survey to community channel.
Questions to Answer
- Is it safe to assume that we may treat any values before the first
non-zero timestamp as having occured on
#0?
Probably No Longer Needed
- Should insert nodes in BFS order
