It also depends on your needs: if you think that you are going to

DJ in CC again - this month's Circuit Cellar includes a photo of the
JTAG adapter as part of my pod's module collection, next month's goes
into the construction and use of it.

development now
Am I correct in thinking that it would be unwise to use these in new
designs? Do you use SPLD? What do you use to program them? How about
the ISP versions?
Look at the XC9536XL from xilinx. It's $1, runs on 3.3v, and ISP-able
or you can program them externally (they're flash based).

actually the space I have is 8x17mm
gak! Yeah, you'd need a PAL to fit it in there. An R8C would fit,
but wouldn't do the job. I can see the status reports: I had an
extra 8x14mm so I added another CPU.

Thanks! Next month's article covers programming the XC9572XL from

Do you know if they fixed the parallel programming in Xilinx ISE with the
most recent version? The last version required a *kernel* driver for
parallel port programming (!!)
I don't know, I built my own JTAG programmer (see the article).
