How to read/write internal signals from gate level

[RuochenDai78]

Hello

Here is my question: for example, there is reg [2:0] a in the RTL code, and after mapping it into gate-level, three DFFs are used to hold a[0], a[1] and a[2] and a is declared as wire type. Then how can I access a in the cpp wrapper?

Thanks

Closing as hopefully that answers it, feel free to post a followup question here.
