3838 - Active-HDL: Warning: KERNEL_0085 "/ir_iic_tb/ir_inst/ir_rcv_0/rcv_data" does not have read access. Use switch +access +r for this region.

3838 - Active-HDL: Warning: KERNEL_0085 "/ir_iic_tb/ir_inst/ir_rcv_0/rcv_data" does not have read access. Use switch +access +r for this region.

Description:
The warning is generated by Active-HDL when some of the signals cannot be displayed in the waveform.

Solution:
To resolve this issue, and get internal signal visibility, set the read access to internal signals through GUI or script.

Using GUI:
1. Go to Design -> Settings -> Simulation -> Access to design objects.
2. Specify the appropriate access for the required signals.
3. Click Apply, and then OK.

Using a script or batch mode:
Use the +access +r switch for the asim command.
