[Pkg-electronics-devel] Bug#1004352: vcd2fst converts 'H' and 'L' to 'U'

Package: gtkwave
Version: 3.3.104-2

Hi,

I have a design that uses weakly driven signals for simulating a board
that has pull-up resistors on an I²C bus. The VCD file contains a 'H'
signal for the times none of the components actively drives the bus, and
gtkwave displays this correctly.

When I convert the VCD to FST for better performance, the weakly driven
signals are converted to 'U', and the signal is shown as a red bar
instead.
