Hi,
I am new to vhdl coding.I am having trouble writing testbench for RAM.Can somebody please help me regarding this?

Thank you.

What exactly are you trying to do? I am more familiar with Verilog, but have used a little VHDL.

 

[atigaddap]

I am trying to write vhdl code for 16x8 RAM.I want to know how to write the testbench module for this.

Like "writing" different patterns and verifying data integrity?

 

[atigaddap]

Yes.Verifying whether it is properly working or not.

 

[melone]

The amount of different tests becomes very large depending on how confident you need to be. What is you final application?

 

[atigaddap]

My final appplication is to write a vhdl code for 16x8 bit RAM where it can perform read and write operations.

FOR WHAT? Are you placing this in an automotive enviornment (temperature extremes)? Or are you putting this in a high-speed computer application (speed sensitive)? Based on the ulitmate system requirements, you can come up with a custom test suite that will allow you to feel more comfortable that your new device will perform in your final system.
