Accessing the Global Timer from the FPGA (Cyclone V SoC)?

Is it possible for the FPGA logic side to access the Global Timer?

Does it involve a memory-access via the FPGA–to–HPS bridge perhaps?

I am interested in capturing the value to resolve event timing across the FPGA and HPS boundaries?

Thanks!

Hello,

Are you trying to access a register from HPS?

You can access any register in HPS by FPGA master through f2h bridge.

If you are trying to access a memory location, say for example your HPS will write a data to memory location, you can access this location by FPGA master through f2sdram bridge.

 

Thanks
