Study, in the moment I working about a project “Implementation a
SVM ( SVPWM) in FPGA with VHDL”.
The PWM Program is already existing and my task is to insert the LUT
and made some changes. So as I am beginner in VHDL, I would like to ask
for a help.
TASK: - Insert in the existing Program the LUT (LOOK UP Table)
dependent of space vector Diagram other states of witching.
Thank u

There is no "Universität Frieberg-Giessen" They are spelled totally differently. I think this is spam having virusses attached.
