* All SPI registers and register bits exposed as human readable names
* Parametrized JESD204B core (also capable of operation with eight lanes)
* The code can be reconfigured, e.g. to support 2 channels at 1 GHz datarate or to support 4 channels at 300 MHz data rate, no interpolation, and using mix mode to stress the second and third Nyquist zones (150-300 MHz and 300-450 MHz).

This work was supported by the Army Research Lab.
The additions and modifications to ARTIQ that were implemented for this project are:
* In ARTIQ, the SAWG and Phaser code: https://github.com/m-labs/artiq/compare/phaser
* The CORDIC core has been reused from the PDQ2 gateware
