Hello,

Could anyone here share a '4 x 512k x 32' SDRAM (e.g. MT48LC2M32) simulation model in vhdl?
I would check a SDRAM controller with ghdl.

Many thanks in advance.

Steve
 

You shouldn't restrict it to VHDL, that part is so old there probably was never a VHDL model written. Most everything from Micron if it even had a model was written in Verilog back in early 2000s.

If you can obtain a Verilog model you'll have to translate it to VHDL so it will run on ghdl.
--- Updated ---

Don't know if this is the part or is similar enough, but going to Micron's website and looking for simulation models for SDRAM this end-of-life part had a Verilog simulation model available https://www.micron.com/products/dram/sdram/part-catalog/mt48lc2m32b2p-5

You will have to translate it as ghdl isn't a mixed simulator.

ads-ee is correct! All Micron models I have come across are modeled in Verilog.
I primarily use VHDL, but since I always use a mixed language simulator so this has never been a problem.

Try to contact Micron if they have (which I highly doubt) and willing to provide your the VHDL model of an old part. Else I am afraid you need to convert manually.
 

Hello,

As GHDL is not a mixed simulator, the model has to be written in VHDL.
I know it is a old part.
However, the goal is to write a controller for the EG4S20 embedded SDRAM and the MT48LC2M32 seems close enough to test all functionalities of my controller.
Meantime, I found a timed functional model of mt48v16m16lf.
Moreover, it seems to be written as a fully parametrizable model.
Will try to change parameters to match my needs.

Do you know of a Verilog to VHDL converter that works well enough?
I saw:
  • V2V SynaptiCAD Tool
  • verilog2vhdl from EDAUtils
Thanks

Steve
