In my humble opinion a PWM peripherals IP(reference design) for MicroZed/Zynq or a tutorial with this topic will be highly acclaimed.
I think it will be very usefull if Avnet/Xilinx would be able to provide IP for PWM peripherals with memory mapped registers. This in order to enable programmatically:
-change the PWM period
-configure the dead-time of the power transistors
-change the polarity of the PWM outputs
-enable or disable the PWM outputs
In my experience a good inspiration for the "state of the art" are the PWM peripherals of TI for the Concerto or Delfino products.
This will considerably help the transition of folks (like me) comming from the microcontrollers domain and trying to migrate to Zynq based products. Since we have little experience in VHDL/Verilog implementation such kind of IP will speed up the transition.
A reference design for Motor Control providing the IP for the main peripherals found on a microcontroller (PWM, ADC, Capture Units/Encoder) will also help the penetration of MicroZed and Zynq.
I could find such a reference design for Altera / competing Cyclone V device but not for Zynq :

Any plans about that?
