FPGA Central

Hi I was trying to program a digilent board featuring xilinx spartan
2E XC2S200E Fpga ...the problem lies with the pin naming. According to
the digilaent manuals the pins are numbered from 1 to 208 where as the
constraints editor in ISE 6.1 the PACE software names this same FPGA
as A1,A2....etc to T16....

My problems comes as I donot know which pin is which so that i can
perform some in/out operations with an expansion board.

please help me with thius
Thanks

Hi Paraag,
Probably you have selected a FG package in your project and that on the
board is a PQ208.

Paraag,
The user manual page 7 describes the mapping between the connector pins
and the Spartan 2E pins.
