Tapeout of PRGA on MPW-5

ORDER PRGA Tapeout

This repository is a branch of the caravel_user_project repository, modified for the tapeout of a 512-LUT4 FPGA generated using PRGA.

A 512-LUT4 FPGA generated using PRGA (Princeton Reconfigurable Gate Array)

• An 8x8 array of CLBs, each containing 8 LUT4s and 8 DFFs and a local programmable crossbar for intra-CLB routing
• 24-track routing channel with L1 tracks
• Capable of implementing 16 out of 30 ISCAS'89 circuits

Design

We used a three level hierarchical design:

• 1x Caravel user project wrapper
  • 1x PRGA top
    • 64x CLB tile
