Hi there, I've just started with CPLD design, using the Digilent Coolrunner II CPLD starter board (Rev. 3.0) and successfully synthesized my code with the Xilinx ISE development software. I would now like to integrate a Cmod breadboardable CPLD module into one of my projects. I don't own a programming cable/adapter, so I was wondering if I could use the Starter Board as a programmer via its JTAG interface. Looking at the schematic, I could not find a way to connect a JTAG daisy chain with another external CPLD, because the JTAG signals are all connected in parallel. Would it be possible to simply not power the CPLD on the Starter Board (detatching JP2) and connect the external CPLD to the JTAG pins? Best regards Stefan
