Hey... i hope there is a clever guy reading this channel and using Protel.... i have buyed a 3rd party FPGA board with a SpartanII SX2S300E... There is onboard Jtag (normal Xillinx Jtag) But when i want to use it with protel and use soft instruments etc... i have to connet "2 Jtags" at one time, one for the Hard Jtag to program the FPGA and one to normal I/O Pins... Quite easy just a multiplexer... but... Their owm Nanoboard has some kind a multiplexer so both chains can be selected at the same time... www.altium.com/learningguides/ AR0130_PCToNanoBoardCommunications.pdf i also hae the schematic here.... I can see on the schematic there is 2 parellel jtags in the parellel cable.. but i can't use the 2'nd as it is... but even more there is a mode and a control bit i dunno if i can do something m,ultiplexing with... Any one haveing a solution exept buying their board ? Regards Kasper
