Hi Alex,

I've been told the Actel Flash FPGAs are quite good. One day I might look
into
that, but it needs to have a free synthesis/fitting (at the least) tool for
VHDL
development to try it.
I don't particularly like the idea of my system core sitting in RAM in an
FPGA,
for various reasons, but anywho.

I'm told by a collegue that Altera nowadays have VHDL free as well as part
of Quartus or MaxPlusII or whatever.
Any comments there Leon, I remember you've used Altera extensively before.

A long while ago I started synthesising a PIC core for the hell of it.
With a 16 bit bus, the whole thing fitted 90% of a 256 macrocell CoolRunner.
I started on a VHDL core of MSP430, but lost interest ..

Anyway, back to LPC2100 I guess :-)

Cheers,
Kris
