A trigger jitter was added by fix on the external trigger input. It
manifests at input sampling frequencies lower than the maximum frequency.
Added the required reset and CE(valid) signal to the last output
stages of the trigger to obtain the desired functionality for all
sampling rates.
The extra delay was added on the trigger and data paths to compensate
for the logic analyzer changes.
The extra delay will be also seen on the m2k daisy chain. The
delay between devices will be increased from 3 to 4 samples delay.
Fix external trigger for low sampling rates.
Because the external trigger can be a short pulse at high decimation rates
there is a high chance that the pulse will be missed.
xsim does not like if a register or wire is used before their
definition. Make sure the every register and wire is defined before it's
used the first time.
The second ADC was removed from the project, as the EV-AD7768-1FMCZ evaluation
board contains only one ADC. Therefore, all the IPs related to the
second ADC have been removed, too.
The data width supported by the spi IPs has been changed from 8 bits to
32 bits, therefore the axis_upscaler(util_axis_upscale_v1_0) and the
m_axis_samples_24(AXI4-Stream Data Width Converter) are no more necessary,
so they have been removed from the design.
The 24 bits width data transfer between the s_axis of axi_ad77681_dma
(AXI DMA Controller) and the offload_sdi of the spi_engine_offload is now made
directly.
Add commands to generate one extra file with resource utilization, in CSV format.
New commands executes only if ADI_GENERATE_UTILIZATION env variable is set.
In ZCU102 LA01_CC_P|N are connected to regional clock, but in order to
receive a device clock properly we have to use pin which is connected
to a global clock buffer. Luckily SYSREF is connected to global clock
pin; swap to port to receive the device clock correctly.
Also, swap the ports in both ZC706 and A10SOC carriers.
mclk now generated by ps not axi clkgen ip. ADAU1761 expects a free
running clock and the i2s driver was switching the axi clkgen ip off
which was causing issues.
