sep_rom_interface_shim

Forward the SEP ROM memory_interface struct onto a prim_rom macro.

ROM_ADDR_WIDTH defaults to 10 (1K 64-bit entries). Forwards read requests from mem_req_i into macro_req_o / macro_addr_o and returns macro_rdata_i on mem_rsp_o. Every request is granted at once and answered with rvalid one cycle later. Writes never reach the macro; they are acknowledged and otherwise ignored.

Parameters

Table 1. Parameters
Name	Type	Default	Description
`ROM_ADDR_WIDTH`	`int unsigned`	`10`	ROM address width; default 10 for 1K entries.

Ports

Table 2. Ports
Name	Direction	Type	Description
`clk_i`	input	`logic`	System clock.
`rst_ni`	input	`logic`	Active-low reset.
`mem_req_i`	input	`sep_sram_req_t`	Memory request from the SEP memory_interface; byte address, 64-bit data.
`mem_rsp_o`	output	`sep_sram_rsp_t`	Memory response: gnt always high, rvalid one cycle after any request, rdata from the ROM macro.
`macro_req_o`	output	`logic`	Read request to the ROM macro (prim_rom); high only for read requests.
`macro_addr_o`	output	`logic [ROM_ADDR_WIDTH-1:0]`	ROM word address: the request byte address divided by eight.
`macro_rdata_i`	input	`logic [SEP_MEM_DATA_WIDTH-1:0]`	ROM read data, returned one cycle after macro_req_o.
