Hello Andy/Sebastian,
My mentor dosen't want to make any change in hardware FPGA cards.
He instead suggest to use Universal Pulse Generator UPG100
http://www.eurias.nl/pdf/UPG100.pdf
However, he wants to control the UPG100 through software, rather than manually
changing the T-On and T-Off times.Are there any such PWM generator devices
available which we can control through software?Or rather build our own PWM
circuits implemented it in MATLAB or PSPICE tools ?

Yes, but the GPIO on the 7i76 is smart-serial. This is why I was
suggesting using some 5i25 pins wired as step/dir on the 7i76 as GPIO
for the purpose.
