Hi Roland,
The idea *is *to utilize the same constraints and container as much as
possible. These common constraints and containers are typically stored in
the platform worker directory and often are symbolic linked in the assembly
when needed. A modern way of organizing them is currently illustrated in
the develop version of the PlutoSDR platform,
https://gitlab.com/opencpi/osp/ocpi.osp.plutosdr/-/tree/develop/hdl/assemblies/include?ref_type=heads
. Inside the assembly directory you will find an include directory that
contains the various ways you can use that platform and its devices in this
case the ADC and DAC.
Taking one of those files in the PlutoSDR assembly directory as an example
and expanding its name: cnt_adc2assy2ic_ic2assy2dac.xml
cnt=container
adc=analog to digital converter
assy= hdl assembly
ic=interconnect
dac=digital to analog converter
analog to digital converter -> hdl assembly -> interconnect (AXI FPGA)
interconnect (AXI FPGA) -> hdl assembly -> digital to analog converter.
