nextpnr-gowin-chipdb 0.7-1 (riscv64 binary) in ubuntu oracular

 nextpnr is a FPGA place and route tool. Its purpose is to turn a
 topological description of digital hardware produced by an FPGA logic
 synthesis tool such as yosys into an elaborate map of connections between
 the hardwired functional units available inside the FPGA's fabric.
 .
 In order to verify the fully implemented design for proper operation at
 high speed timing-analysis of the design is also supported.
 .
 This package contains the chipdb FPGA layout description files.
