I've found that 1-connection nets (in this case,
a resistor and a pad, where the pad has no
"guts" but does have a pin) are highlighting
but the window that pops for more serious
errors does not appear.
I can't figure out how to make that window
show on command, only as an outcome of
bad netlisting. Evidently the 1-connection
nets are not inhibiting netlist creation. Maybe
it's "netlist_has_failed" that triggers the error
window to pop? I would not be bothered by
it popping every time, with "No Prob!" result.
Maybe that can be an option.
It also seems that the "connect" symbol
was throwing mystery "shorted net" errors
although all I could find attached, were
"VPOS" net_label and live devices. I had to
remove them and make a new RMET
resistor. What I was looking for with "connect"
is a behavior like the Cadence presistor,
which will netlist as a valued R for Spectre
but as a short-across (joining different-named
nets) for LVS schematic netlisting. But there
seems to be something else going on, as is.
I would like to talk about LVS schematics and
modalities of this sort, but I am pretty far
from any traction on that front.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
I have added an xschemrc variable show_infowindow_after_netlist.
If you set show_infowindow_after_netlist 1
in your xschemrc file the erc window will pop up always after netlist even without critical errors.
Currently the idea is to NOT pop up this window for warnings (example: nets that are driven but not used by anyone, this is not necessarily an error,).
