XBAR_DEMUX_BUS s_core_bus(); // Internal interface between CORE <--> DEMUX

the s_core_bus is defined as a XBAR_DEMUX_BUS, but the additional signals provided by this bus (compared to XBAR_TCDM_BUS) are not used. Would it make sense to change this bus and simplify the code?

Additional signals:

• barrier (0, not used)
• busy (not connected, not used)
• exec_cancel (0, not used)
• exec_stall (0, not used)
• r_gnt (0, not used in connected module(demux))
