simulation a custom peripheral

[mahound]

hi
I want to create a microblaze and add a custom peripheral such as some registers. and also the value of registers are changed by C program in SDK. eventually, I want to simulate the project.
I made this project in PlanAhead 14.2 and simulated it. but there is some problems: I can't see any changes in the value of registers in output of simulation while these values are changed in C program.
is there any tutorial (as video or documentation) that it shows a similar project?? (indeed, I want to simulate it!!)

Yes there is plenty of tutorial but may i solve your problem earlier.Are you use XPS?

You might not have run the simulation for a long enough period of time.

My take on this is if you want to build a microblaze system. Run submodule simulations on the custom peripheral and then stick it into a XPS system with the microblaze, and download the image onto a board to test it. Running simulations that take 100's of ms to run are no fun.

yeah, first I have launched PlanAhead and then XPS. I have explained the steps of my operations in link below:

but there wasn't anybody to help me.

thanks,

I run it for 1 second but there wasn't any change!!
I prefer to simulate because it isn't possible for me to have a board. hence I want to simulate my project and that is foremost for me.

kind regards

Did you load your RAM with the compiled sw image?

Make sure you see address/data for the BRAM that is used as the reset vector. If you don't see the correct data or you see the microblaze fetching U's or X's then you'll need to determine why the BRAM initialization isn't done.

thanks for reply
I don't have anyidea about loading RAM!! I thought that the operation will be done automatically.
How can it be loaded?

indeed, I must say that I follow the instruction of PDF which is attached here. there isn't any words about loading RAM!
