I was trying to write a verilog code for a memory module which has has a bidirectional inout port for the data. But I also want to output high impedance during write or if MEM_OE(output enable) is not set. But
Title: Re: How modeling static RAM in Verilog Post by: nctnico on November 01, 2024, 03:10:04 pm Generally speaking: if you infer asynchronous RAM, the synthesizer will be forced to use flipflops and/or LUTS. With synchronous RAM, the synthesizer can choose what is most efficient (sync...

This has the advantage of having a faster rise from 0 to 3.3V (or 2.5V) than the first solution. This is sample code for how to achieve the fast rise in VHDL: library IEEE; use IEEE.STD_LOGIC_1164.ALL; entity top is Port ( data : in std_logic; data_to_pin : inout std_logic...
2. after using above sopc builder component, do i have to use eclipse software for using sdram? or use verilog code to write/read sdram. 3. if i must use software for sdram data inout, I want to write some data to address of sdram, and read data from address of sdram using Nios...

It seems like overkill to use QSYS with NiosII though, plus I'm not very familiar with it. What's resource will help me implement this controller as a 2-port RAM entity in the simplest way possible? entity sdr_sdram is generic( ASIZE : integer := 23; ...
