Warning: KERNEL_0085 <signal name> does not have read access. Use switch +access +r for this region

Description

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

Solution

To get internal signal visibility, you have to set the read access to internal signals.

If you use the 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

If you use a script or batch mode:

Use the +access +r switch for the asim command. For example:

asim +access +r ...
