Building

Needs migen and Xilinx ISE. Assumes ISE is installed in /opt/Xilinx.

make

Flashing

With Digilent JTAG HS2 cable:

  • download firmware to dongle. Manually (adjust USB bus as needed):
/sbin/fxload -t fx2 -I /opt/Xilinx/14.7/ISE_DS/ISE/bin/lin64/xusb_xp2.hex -D /dev/bus/usb/001/*`cat /sys/bus/usb/devices/1-3/devnum`

or automatically via the udev rule:

SUBSYSTEM=="usb", ACTION="add", ATTR{idVendor}=="0403", ATTR{idProduct}=="6014", ATTR{manufacturer}=="Digilent", RUN+="/usr/bin/fxload -v -t fx2 -I /opt/Xilinx/14.7/ISE_DS/ISE/bin/lin64/xusb_xp2.hex -D $tempnode"

  • install xc3sprog

  • flash_xc3.sh jtaghs2

  • look for Verify: Success

Mirny CPLD gateware features

Hardware

https://github.com/sinara-hw/mirny/wiki

CPLD Gateware design

  • SPI prefix-based based router (4 PLL, 4 ATT, 4 registers)
  • Use only one CS, one EEM
  • Independent access to RF switches as high resolution, high speed, contention-free RTIO TTL channels
  • Configure RF switches via dedicated SPI register to allow saving RTIO/IO resources
  • Read MUXOUT via EEM TTL RTIO (for precision timing measurements) or via SPI register
  • IFC_MODE read-out
  • Green LEDs driven from RF switches
  • Red LEDs driven from !MUXOUT or bypassed
  • Individual access to attenuators, not daisy-chained
  • Fully configurable clocking, chip-enables, ATT reset, LVDS modes, MUXOUT routing modes
  • Configurable mezzanine IO, bidirectional, GPIO register style, with option of routing 4 EEM IO to the mezzanine
  • Documentation, flashing/deployment scripts

Status

This code and rudimentary ARTIQ coredevice support (without PLL register abstraction) are available for funding.

Gateware in release v0.3

Would it be possible to post the built gateware in the latest release files (v0.3), similar to the previous release (v0.2.4)?
