2.5.2.1. PHY Lite Interface
This module models the core logic. Apart from the ports listed in PHY Lite IP Instance and Tester Port Connections table, additional ports for this module are shown in the following table.
Port | Type | Description |
---|---|---|
reset_n | Input | — |
core_clk | Input | — |
repeat_count | Input | Tester repeat count |
pl_wrdata_en | Input | Write enable from core |
pl_rddata_en | Input | Read enable from core |
pl_rddata_pass | Output | Read pass |
pl_rddata_fail | Output | Read fail |
In the write test, this module provides the enable signals for data and strobe, the strobe pattern, and random data generated by the PRBS channel.
In the read test, it provides the read enable signal from core, receives the data and strobe and performs a check using a PRBS channel, and provides the corresponding read pass or read fail signal. There is also reframing logic to find the frame offset in LINK mode.
