History

Jared Boone 4878be8213 New .svf to reflect slew rate and IO standard changes in prior commits.

Changed name of .svf file to "default.svf" to match what ISE iMPACT wants to write out from "One Step SVF" (a.k.a. "Expresssvf").

README.md

Added link to Dangerous Prototypes information on how to switch buffers in Bus Blaster v2.

sgpio_if.xise

Initial implementation of MAX5864 <-> SGPIO interface via Xilinx CoolRunner-II CPLD.

top_tb.vhd

Eliminate ill-conceived HOST_CLK from CPLD.

2012-06-14 19:08:20 -07:00

top.ucf

Remove FAST attribute from all CPLD I/O, since it changes slew rate by less than 1ns -- not enough to be important at 20MHz or so. Will re-examine later, if we try to push bus speed higher on the final board rev.

top.vhd

Eliminate ill-conceived HOST_CLK from CPLD.

README.md

CPLD interface between LPC43xx microcontroller SGPIO peripheral and MAX5864 RF codec.

Requirements

To build this VHDL project and produce an SVF file for flashing the CPLD:

Xilinx WebPACK 13.4 for Windows or Linux.

To program the SVF file into the CPLD:

Dangerous Prototypes Bus Blaster v2:
- Configured with JTAGKey buffers.
- Connected to CPLD JTAG signals on Jellybean.
urJTAG built with libftdi support.
BSDL model files for Xilinx CoolRunner-II XC264A, available at xilinx.com, in the "Device Models" Support Resources section of the CoolRunner-II Product Support & Documentation page. Only one file from the BSDL package is required, and the "program" script below expects it to be at the relative path "bsdl/xc2c/xc2c64.bsd".

To Program

./program

...which connects to the Bus Blaster interface 0, sets the BSDL directory, detects devices on the JTAG chain, and writes the sgpio_if.svf file to the CPLD.
