Associating timing specification groups on the NET declarations. Updated setup/hold constraints -- old constraints were incomplete and possibly incorrect, though I'm still not *positive*.
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".
Generate an XSVF
After generating a programming file:
- In the ISE Project Navigator, "Processes: top - Behavioral" pane, double-click "Configure Target Device".
- Click "OK" to open iMPACT.
- Ctrl-N to create a "New Project".
- "Yes" to automatically create and save a project file.
- Select "Prepare a Boundary-Scan File", choose "XSVF".
- Select file name "default.xsvf".
- Click "OK" to start adding devices.
- Assign new configuration file: "top.jed".
- Right-click the "xc2c64a top.jed" icon and select "Erase". Accept defaults.
- Right-click the "xc2c64a top.jed" icon and select "Program".
- Right-click the "xc2c64a top.jed" icon and select "Verify".
- Choose menu "Output" -> "XSVF File" -> "Stop Writing to XSVF File".
- Close iMPACT.
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.
