nextpnr-ice40-qt binary package in Ubuntu Mantic ppc64el

 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
 speed timing-analysis of the design is also supported.
 .
 nextpnr-ice40 supports the Lattice iCE40 series of FPGAs and uses the
 hardware description chipdb from the fpga-icestorm package.
 .
 This package supports both the GUI and command-line interfaces. A slimmer
 command-line only version is available in the nextpnr-ice40 package.
