# ghdlsynth-beta
VHDL synthesis (based on ghdl)
This is awfully experimental and work in progress!
## How to build
FIXME: should provide an easy way to build as a module!
Get ghdl from github,
build and install
build and install libghdlsynth.a:
```sh
$ make libghdlsynth.a
$ make install.libghdlsynth
```
Get yosys.
From ghdlsynth-beta:
Patch yosys sources using yosys.diff
Copy the ghdl/ directory in yosys/frontends
Configure yosys.
In Makefile.conf, add:
```makefile
ENABLE_GHDL := 1
GHDL_DIR := <ghdl install dir>
```
Build yosys.
## How to use
Example for icestick:
```sh
ghdl -a leds.vhdl
ghdl -a spin1.vhdl
yosys -p 'ghdl leds; synth_ice40 -blif leds.blif'
arachne-pnr -d 1k -o leds.asc -p leds.pcf leds.blif
icepack leds.asc leds.bin
ceprog leds.bin
```
