[Gtkwave-users] Signals list display, hier max setting and signal names with \

[Walter F.J. M. <w.f...@re...>]

Hallo,

I'm using
   - Xilinx Vivado 2016.2
   - post-synthesis vhdl models generated by netlister
   - ghdl 0.34dev with ghw output
   - gtkwave V3.3.73

The generated models have sometimes signal names with '\', like

   top.tb_arty.uut.rlink.core.b2cd.\N_REGS[dataval]\

When I add them to the display the full hierarchy path is shown.
That happens for any 'hier max' setting larger than 1. An exception
is 'hier max' set to 1, in that case only the last name component
is shown.

See attached screen shot for 'hier max' equal 3, the signal
names without '\' are shown with 3 name components, the ones
with '\' with all, starting from 'top.'.

This is quite a nuisance because the 'Signals' pane is always as
wide as the longest name, and since full hierarchy path names tend
to be rather long in generated models, the 'Waves' pane gets
uncomfortably narrow.


		With best regards, 	Walter


P.S.: Note that Vivado even generates signal names like
        top.tb_arty.uut.\SMRB.I0\.\<const0>\
        top.tb_arty.uut.\SMRB.I0\.smrb.\RB_SRES[err]\

       --> "SMRB.IO" apparently is one element of the hierarchy
       --> gtkwave handles that correctly in the SST display
       --> but again, always full path shown in 'Signals' pane
