Hello there , i have a nexys 4 Board,i'm working on to profile a C program using SDK(software development kit) with cortex-M0.

I 've to create a design Block using vivado to export it to SDK but  the problem is that the cortex-m0 was not predifined.

i want to know if i could have a design block from a .v file

Also,i've another question,I'm trying to measure the execution time of a process using systick,

i' using that:

SysTick->CTRL =0 ;

  SysTick->LOAD=0xFFFFFFFF ;

  SysTick->VAL=0;

   SysTick->CTRL =0x5 ;

starttime=SysTick->VAL;

is there anyone can help me?
