# Unstable IceStorm module
|
|
|
|
|
|
|
|
|
|
|
|
This module provides is available since version 0.45.0.
|
|
|
|
|
|
|
|
|
|
|
|
**Note**: this module is unstable. It is only provided as a technology
|
|
|
|
|
|
preview. Its API may change in arbitrary ways between releases or it
|
|
|
|
|
|
might be removed from Meson altogether.

## Usage
|
|
|
|
|
|
|
|
|
|
|
|
This module provides an experimental to create FPGA bitstreams using
|
|
|
|
|
|
the [IceStorm](http://www.clifford.at/icestorm/) suite of tools.
|
|
|
|
|
|
|
|
|
|
|
|
The module exposes only one method called `project` and it is used
|
|
|
|
|
|
like this:
|
|
|
|
|
|
|
|
|
|
|
|
is.project('projname',
|
|
|
|
|
|
<verilog files>,
|
|
|
|
|
|
constraint_file : <pcf file>,
|
|
|
|
|
|
)
|
|
|
|
|
|
|
|
|
|
|
|
The input to this function is the set of Verilog files and a
|
|
|
|
|
|
constraint file. This produces output files called `projname.asc`,
|
|
|
|
|
|
`projname.blif` and `projname.bin`. In addition it creates two run
|
|
|
|
|
|
targets called `projname-time` for running timing analysis and
|
|
|
|
|
|
`projname-upload` that uploads the generated bitstream to an FPGA
|
|
|
|
|
|
devide using the `iceprog` programming executable.
