well... the CPLD I'm using is in a BGA package (which means I can't
attach leads to the pins), and another device on the JTAG chain got
stuck in reset, so the chain 'broke' and couldn't be accessed. That's
why I was asking

Unless you're storing crytographic keys in the CPLD, what's the point
of erasing it without using JTAG?

For erasure, thermite works too. A hammer may work but is not as certain.

As far as I know, the only way to erase/program Xilinx CPLDs is via
JTAG.

Working with a coolrunner2 CPLD. Is there a way to erase whatever has
been programmed into the CPLD, without using JTAG?
