i want to design 4 bit full adder(signed and unsigned)
also i need testbench for that vhdl code
could you help me?

I was thinking of a condition where
Uvalue, an unsigned number is multiplied by Svalue a signed 2’C number, which is then assigned to Zvalue or Zvalue = Svalue* Uvalue.

This is a question that cannot be answered in a comment.
Basically if you can do it with a microcontroller, it is better to use a microcontroller.
FPGA should be used when you have real-time requirement that cannot be achieved or are difficult to achieve using microcontroller.
BTW, I will write a post on it.
Thank you for the question
Ciao

I’m a newbie and very beginner in FPGA. I have a question regarding with FPGA and Microcontoller uses in digital electronic system. For what system/cases that is better to use FPGA and in other case we should use microcontroller?

Thank you

hi, maybe the best solution is a microcontroller. Why do you want to use an FPGA?

i want to design and implement in FPGA a controller for a new hoverboard. the controller will be implemented in the FPGA fabric and designed to drive the motor in 3 speeds: the 95%, 50% and 10% of the maximum speeds. do you think you can help me out with guidelines on writing the codes. thanks.

which code did you copy and paste?

The error was in the compilation section. “TDF syntax error”
Help me please.
