wb_ram

wb_ram is a generic memory that is intended to map against on-chip RAM or registers. It is currently hard coded to use 32 bits and has a Wishbone B3 interface for burst accesses

Parameters

Name	Description	Default value
dw	Wishbone data width	32 (only supported value)
depth	Memory size in bytes	256
aw	Address width	clog2(depth)

Test bench

wb_ram comes with a self-checking test bench that uses the wb_bfm_transactor from wb_bfm.

TODO

• Make width configurable
• Add technology-specific backends
• Only allow wrap bursts less than memory size
