sir,
i am designing dsp and fpga interface board and also try to design code of gel file. i take reference of TMS320C6455 development board support while designing schematic and for gel file i take support of c6455.gel of spectrum . but in our previous version gel is not working . we are not using CPLD,PCI. I am interface fpga on j4 and j3 pin of TMS320C6455 development board. DDR2 RAM is same as on TMS320C6455 development board so where is problem in gel or in schematic. my clock and power supply is ok.
