もう、10月も終わりに近づいてきた。
最近はなにもやってないのでつぶやくことも少なくなってきた。
久々にメモリしておきたい作業を行ったので備忘録を示しておく。
SymbiFlowをいうFPGAのツールを試してみた。
詳細は下記のURLを参照すると良い。
https://symbiflow.github.io/index.html
下記のリポジトリをcloneしてサンプルを動かしてみる。
https://github.com/SymbiFlow/symbiflow-examples
サンプルで合成できるデバイスは次の2つである。
今回、試したのはもちろん、Xilinx 7 seriesです。
ARTY 35、ARTY 100、BASYS3のサンプルが用意されている。
手元にARTY 100があるので合成してみた。
実行するのはhttps://github.com/SymbiFlow/symbiflow-examplesに記載されていること、そのままである。
まずはcloneする。
$ git clone https://github.com/SymbiFlow/symbiflow-examples.git && cd symbiflow-examples
