SOFA/FPGA22_HIER_SKY_PNR/README.md

FPGA22_HIER_SKY_PNR

2x2 FPGA designed using hierarchical flow and SKY130_FD_SC_HD.

Updates

• Merged grid_io modules with connection blocks
• Pre-routed scan chain signals
• Created carry_chain feedthrough between grid_clb modules
• Prerouting global signals (Test_en)
• Prerouting clock signals
• Enabled Feed through generation for clock
