Inout port problem

Hi,

I'm AlexGil, and I trying to design a simulator for an external sram before to choice and buy .

 

According to the datasheet (from Issi) I see the data port is bi-directional so I design my vhdl to capture this case.

 

When I try to put some data into the RAM everything goes fine but when I try to rea the same location I see on the simulator the value 0x0x0x0x.

 

I try everything  without any success .

 

I add the vhdl of the component and the test bench for the same...

 

I'm very glad if someone tells me where I'm wrong...

 

thanks a lot

Hi..

 

which tool you are using for simulation.

 

I tried simulating your files in modelsim-6.5 .. seems its working fine. 

 

The snapshot of simulated wave is attached..
