DC sweep down-count does not plot results

Thread Summary

The user reported an issue with downward sweeps in .DC directives not plotting results in the simulation, with a log message indicating a corrected increment sign. The problem was confirmed in the current version but works correctly in versions V17 and V24.1.8. The support engineer acknowledged the issue and stated it will be corrected in the next release.

When using a down-count in a .DC directive, the simulation itself appears to run, but the results cannot be plotted.

In the attached circuit, the sweep in the upward direction behaves correctly:

.dc V2 0 5 0.1


However, when sweeping downward, the data is not plotted and the following message appears in the log:

HystComp.net(11): Corrected wrong sign of increment.
.dc V2 5 0 0.1
^^^^


If I change it to:

.dc V2 5 0 -0.1


the log message disappears, but the results still do not plot.

I tested with older versions and confirmed the following:

V17: both upward and downward sweeps work correctly

V24.1.8: also works correctly
