projects: ad5706r: coraz7s: add project by actorreno · Pull Request #1997 · analogdevicesinc/hdl

actorreno · 2026-01-27T04:45:54Z

PR Description

The AD5706R devices are 4-channel, 16-/12-/10-bit resolution, low noise,
programmable current output, digital-to-analog converter (DAC) capable of
multiple operating modes and output current ranges with high power efficiency.
The family provides multiple programmable output current ranges up to 300mA.

The project uses SPI engine to reach 50MHz transactions on CoraZ7S FPGA.

Normally we use Zynq

Pro tip: you can navigate to an anchor
https://analogdevicesinc.github.io/hdl/projects/ad9081_fmca_ebz_x_band/index.html#cpu-memory-interconnects-addresses
Then use
Ctrl+Shift+alt+RightArrow (or Ctrl+Shift+alt+L) to navigate to the next page at the same anchor, so it is fast/easy to compare patterns.

for both create at /documentation, please

i actually thought this was ok to be placeholders

i actually am not familiar with mbed/iio and no-os so i can't create their docs

will just delete these, i've been told the wiki isn't as important as the github docu too

v2:

Applied minor corrections in index.rst from reviews
RTL was requested to remove PWM and DMA now that I used light version of SPI Engine

 - updated the block diagram to remove pwm/dma

 - removed some entries in the docu regarding the pwm/dma

+ad_ip_parameter spi_clkgen CONFIG.VCO_MUL 1


spi_clkgen is set to output 10MHz which seems wrong. It should be configured to output the maximum frequency intended to be used by the design - usually 2x the max SPI SCLK frequency.
also check the parameter validity since not all combinations are valid. vivado will throw out a critical warning when they are not. right now you have the following:
[DRC AVAL-46] v7v8_mmcm_fvco_rule1: The current computed target frequency, FVCO, is out of range for cell i_system_wrapper/system_i/spi_clkgen/inst/i_mmcm_drp/i_mmcm. The computed FVCO is 50.000 MHz. The valid FVCO range for speed grade -1 is 600MHz to 1200MHz. The cell attribute values used to compute FVCO are CLKFBOUT_MULT_F = 5.000, CLKIN1_PERIOD = 10.00000, and DIVCLK_DIVIDE = 10 (FVCO = 1000 * CLKFBOUT_MULT_F/(CLKIN1_PERIOD * DIVCLK_DIVIDE)).

changed and patterned to other SPI engine projects, basically VCO_MUL 8 and CLK0DIV 5 for 160 MHz setup

clkgen issue is still present in latest commit

Since there is only one supported evaluation board, there's no need to create a bullet point list.

v4:

simplified architecture, does not use spi_engine anymore and related IPs.
removed mention of those IPs in documentation

This change is to reflect the linux driver and the discussed requirements that makes this
simplification acceptable
