PCI Express

hi.

i m new to PCI express.

in one of our design we are using SPARTAN-6 based board with PCI-express interface.

can anyone help me by telling what are the main hurdles to pass the design in software and hardware wise.

thanks,

Bharathi

Hi,

I think you should focus on getting the example design provided to come up and run on the SP606 board. This would familiarize you with different aspects of the design process using the core.

hi,

thanks for your suggestion.

ya we are referring SP605 spec. main hurdle in our case is, FPGA taking 172ms to boot from SPIx4.this configuration timing how can i reduce???

Hi,

Doesnt th eSP605 also have a x16 BPI configuration option. I think that would be faster. Although I have not looked at this board lately so it might be best to check the Board UG to be sure.

If you are plugging into a standard system with an ATX power supply 172 ms config time should be OK because you have the 100 ms from power stable plus an ATX supply provides a 100 ms buffer before power stable is asserted.

I am not new to PCIE.I have a design for ML555 but not for ML506, I leave my college and now I just have a board ML506.So Where can I get a Example for PCIE on ML506.Thank you

If you have tried google then you must found ML506 PCIe x1 Endpoint Design.

However for ML506 here is the link for its reference designs.
