BoW die-to-die link layer
Maturity plannedTargets FPGA + ASICDifficulty HardPriority 3
Bunch of Wires link layer with slice-level framing, optional FEC and lane repair for parallel die-to-die interfaces on standard and advanced packages.
Planned. This block is specified in the catalog with its interfaces and targets. No implementation exists yet; the skeleton command below generates a lint-clean shell with its ports and registers.
Interfaces
| Port | Direction | Kind | Width | Notes |
|---|---|---|---|---|
| ctrl | in/out | APB control bus | 32 | Control and status registers, including ID, VERSION and STATUS |
| irq | out | interrupt | 1 | Interrupt request |
| phy_tx | out | parallel | 256 | |
| phy_rx | in | parallel | 256 | |
| tx | in | AXI4-Stream | 256 | |
| rx | out | AXI4-Stream | 256 |
