Simply RISC S1 Core - Synthesis Environment

===========================================

The scripts to run synthesis are similar to the ones

used for simulations, you can still use the free Icarus

Verilog software (that will target an FPGA application)

or a commercial Design Compiler tool from Synopsys (that

will be used for ASIC). In addition there is also a good

synthesis tool for FPGAs from Xilinx named XST (could be

"Xilinx Synthesis Tool").

To synthesize using XST:

  s1_synth xst

With Icarus you will use the "fpga" target, to do so

just run:

  s1_synth fpga

If you want to use Synopsys Design Compiler instead you

have to use:

  s1_synth dc

Please note that the commercial tools are NOT supported, and

they will probably not work unless you fix all the required

parameters properly (we are focusing on free software since

we want to build up a community of developers around the S1).

The results for these scripts are in the directories:

  run/synth/xst/

  run/synth/fpga/

  run/synth/dc/
