Sanity check for very first FPGA circuit design

r2kordmaa

Hi

 

I have played around with couple of Spartan3 FPGA boards, but have never designed a FPGA circuit before

so here goes small step for mankind, giant leap for me

 

I designed my circuit around SC3S200A(Spartan3A), in a 100pin QFN package

I have done my best, but without prior experience in FPGA circuit design, that might not be enough,

any problems in secondary subsciruits i can deal with, but if FPGA fails to run i have waisted substantial sum on PCB and components

I would rather like to avoid that

 

So would anyone with experience on designing Spartan3(A) circuits be willing to take a look at my design and tell me if the design has any chance of working?

I have attached the schematic PDF

 

Primary consern is page 2, JTAG and boot configuration.

 

FPGA power is on page 3 and IO banks on page1, but i think its unlikely there are problems on these pages that might brick my design

 

Rest of the circuitry is mostly unrelated to FPGA and if some of that doesnt work, its not a huge problem

 

thank you in advance

  • Thank you for the tips John, i'll make sure to implement them

     

    I'm also a strong believer in design reviews, one never sees his own mistakes. I myself have demonstrated that way too often

    Unfortunately none of my collegues have any exp at all in fpga design, havent had the nessesity in our line of work really(industrial automation machinery)

    I can however do better than an artist for design reviewing,

    One of my friends works in a company that does make fgpa circuitry daily.

    I think im gonna pay him a visit next week and try to steal half an hour of some engineers time
