# XLS experiments
The `shell.nix` fetches the binaries distributed in
the [releases](https://github.com/google/xls/releases).
The distributed XLS binaries have very technical names that don't make sense
for end-users and uses some naming-conventions with underscores.
Rename them to always have an `xls-` prefix for tab-completion discoverability,
replace underscores with dashes and remove the superfluous `_main`.
This provides the binaries `xls-ir-converter`, `xls-interpreter`, `xls-opt`,
`xls-codegen`, `xls-proto-to-dslx`, `xls-prove-quickcheck`.
Also, sets up an environment variable `DSLX_PATH` with the stdlib path.
Also `dslx-fmt` and `dslx-ls` have friendlier names.
See https://google.github.io/xls/dslx_language_server/ how to set up language
server (but use the nicer binary name with dash).
## Building
This uses a simple makefile for ease of use and clarity what is going on.
## To use
Given a foo.x file,
* `make foo.opt.ir` builts an optimmized ir.
* `make foo.test` runs all the unit tests in the given *.x file.
* `make foo.sv` generates system verilog.
Current assumption is that top is called `top` (configured in Makefile).
## Convolve experiment
This should eventually become a proc that takes a sample (e.g. audio sample)
and runs a convolution over it (e.g. to get a FIR filter). Also prepared for
time-multiplexing a convolution core, so that each input can take multiple
cycles to generate one output.
```
make convolve.sv
make convolve.test # to run tests
```
