RAL UVM_ERROR: get: unable to locate hdl path mem_dut.mem[5] # Either the name is incorrect, or you may not have PLI/ACC visibility to that name

Hi,

I am compiling the mem_dut with the nvopt option in questa sim still its not able to find the hdl path , what may be the posible causes ?.

And i am sure name is correct.

When you state that you are using the ‘novopt’ option when compiling, what do you mean? Using ‘novopt’ is highly discouraged and there are better ways to achieve design visibility.

If you are using the recommended 3-step flow, you can use the ‘+acc’ option during the ‘vopt’ step. If you are using a 2-step flow, you can use ‘-voptargs=+acc’ during the ‘vsim’ step.

If you can post the commands you are using to compile and simulate along with the exact error message, additional guidance can be provided. Of course, contacting your Mentor support representative is always recommended.

Thanks for your response.
I removed -novopt option from compile target. and add +acc=r it start working . But i have seen the SPI example using ral, there, in compile target -novpot option is enable. Why using ‘novopt’ is highly discouraged ??

‘-novopt’ is a legacy switch that is used to maintain backwards compatibility. It removes all optimizations and makes simulations run extremely slow which is why it should never be used. Using the +acc option allows you to maintain only the visibility specifically required for your environment so that the simulations run as fast as possible.
