The Arachne-PNR build converts the IceStorm text chip databases into the arachne-pnr binary chip databases. Always rebuild Arachne-PNR
after updating your IceStorm installation.
Both place and route tools (Arachne-PNR &amp; NextPNR) convert the IceStorm
text chip databases into the respective PNR binary chip databases during build.
Always rebuild the PNR tools after updating your IceStorm installation.
