FPGA Diagnostics

hai,
Can i get some information regarding FPGA diagnostics.
1.How to check whether a FPGA is configured or not?
2.How to check the IO standard used by the FPGA?
Please suggest some relevant links for FPGA Diagnostics.

Thanks & Regards
Linu Cherian
 

Re: FPGA Diagnostics

You make a counter and flash an LED when counter tapers. This will check your required I/O and of course the configuration of FPGA.
 

Re: FPGA Diagnostics

The FPGA is configured whan the DONE pin is released. DONE is an open-drain output.

So, you need a pull-up at the DONE pin too. You could also connect multiple FPGA DONE pins togetter, and this way, when every FPGA have programmed, will this network goes to 1 (and enter FPGA into run mode).

As for the IO standard, the easiest way, once you ran the P&R, is to look at the generated log files. Some of those files are actually intended to be read! To make sure everything is OK.
