Atmel CPLD Test Rig

Post by BigDumbDinosaur »

Atmel makes a programmer/tester for their ATF15xx CPLD series, which includes the ATF1508as I plan to use in POC V2. This unit works through a standard Centronics port on a PC and is powered by a 9 volt DC wall wart. Here are some pictures.

In the above pictures, I have loaded a test fuse map into an ATF1508as, the purpose of which is to exercise some of the outputs and prove that the CPLD and the test rig are working.

That's alot of hardware compared to Xilinx CPLD's which just need a J-TAG port and programming cable and the free software. I think they still have PLCC packages available too.

It's a device test rig as well as programmer. If programming is all that is needed a simple JTAG hookup will suffice, like with the Xilinx parts.

I decided to get this unit so I could play around with the logic after written into the CPLD. There are some 7-segment displays, LEDs, push buttons, etc., all of which can be used to see what happens when input X goes high or input Y goes low. There is also an embedded clock generator for testing logic where a clock signal is involved.

Atmel makes different adapters for this unit so various package sizes and types can be supported. The unit ships with a 44 pin PQFP adapter, as well as some sample CPLDs in that package size. The version of the ATF1508as I plan to use comes in a PLCC84 package, so I also got one of those adapters.
