VHDL: Single-Port RAM



This example describes a 64-bit x 8-bit single-port RAM design with common read and write addresses in VHDL. Synthesis tools are able to detect single-port RAM designs in the HDL code and automatically infer either the altsyncram or the altdpram megafunctions, depending on the architecture of the target device.
