Default spartan-3 starter kit board

Hi everybody

Sorry for the basic question. I'm starting with FPGA and I'm using a
Spartan-3 Starter Kit
board. I would like to be able to implement a design using microblaze,
let's say one of
xilinx's microblaze reference designs, in a way that it runs at
power-on. Do you know of a
documentation that explains how to do that?

Tanks

Hi J

You probably mean that you would like to use non-volatile memory (PROM)
for bitstream storage. For that purpose you need to convert the
bitstream
(updated with executable.elf if you intend to use microprocessor in
your design located at #project root#\implementation\download.bit) into
PROM.mcs file used for programming PROM. For mcs file creation and
downloading use ISE's accessory iMPACT.
iMPACT's nice wizard will guide you through this (ver 8.1). Select
Prepare PROM file -> Xilinx PROM, MCS file format, PROM filename and
location -> Select proper PROM (xcf0xs - look at StarterKit User guide)
-> Add -> Find your bitstream file -> Clik to -> Generate file and
voila the mcs file is prepared.
Connect the device to JTAG cable!!!!! Then run Boundary Scan (and press
Cntrl+I for Initialize chain). Select generated mcs for PROM (and maybe
files -bit, bmm, elf for directly loading Spartan3). With right click
on the device and program it.

Have fun

Guru
