Looking for MT48LC2M32 simulation model in vhdl

[Steve_7467]

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.

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
