stoping AXI Write requests

[pawangupta]

Hi All,

Suppose a Bus master (Processor) request continuous write transfers to an AXI slave, & i am having limited memory to store those write data & because of my hardware processing delay, memory are not instantly vacated.

Is it possible to stop the Bus master to initiate further write requests as i am not having enough memory to store those data till some of the memory space gets free???

Say, i am having just X memory space, and after X memory space is occupied with some X writes. I need to tell Bus Master not to send write data any more...

Is there any AXI feature which can help...OR other options..




Please help me to get this...

Thanks,
Pawan.

you can add some delay for write transfers!

you want to do verification for AXI slaves using OVM model? or you want to design AXI slaves using delay features?
