Enum names not saved in the vcd

[ArcSpecter]

For some tpical enums used for FSMs looking like:
localparam integer XBAR_W_FSM_STATES = 7; typedef enum logic [$clog2( XBAR_W_FSM_STATES )-1:0] { S_IDLE, S_QUEUE_WAIT, S_QUEUE_READ, S_REQ_WAIT, S_WRITE, S_BRESP } xbar_state_t;
The vcd does not contain the enum names for states, one has to do manual mapping with text files, its doable but painful during the development when you change/add states.

So is it the way it supposed to work or will it be fixed? I heard verilator does export enum names, so I wonder if iverilog would be planned to do same.

The VCD will likely never contain this since it is specified in the standard and does not currently have support for this functionality.

It would likely be possible to add this to FST. which is likely what verilator has done.

I'll treat this as an enhancement request related to the FST dumper.
