Build Status Coverage Status

This repo contains some Migen modules created to support some MiSoC features on the Xilinx Zynq SoC. A Zedboard is used for testing, the existing platform from Migen is used as baseline and extended as necessary.

Cores

  • wrapper for PS7

Interconnect

  • AXI2CSR
  • P2P interconnect
  • InterconnectShared
  • Crossbar
  • Writer, AXI3 Slave + CoreLink DMA-330 DMA Controller Peripheral Request Interface (PRI)

By now only P2P interconnect is in actual use, where M_AXI_GP0 is wired to a custom AXI3 slave and M_AXI_GP1 is wired to a AXI2CSR bridge.
