Feature Request 72 - "Printing hidden errors to terminal" suggests
...
showing errors in XSPICE code model support functions by default.
But errors may occur routinely and be handled by code.
To aid developers, setting variable "noisyxspice" will display the messages.
Also fix an error report in cm_event_queue(), remove XSPICE parse error
messages that are now shown twice and fix errors in d_source that
were seen with the new error reporting.

Add new capabilities to the adc/dac_bridge XSPICE code models.
...
If either bridge has a single analog connection and two or more digital
connections it will act as a conventional multi-bit ADC or DAC.
When the low threshold is higher than the high threshold, adc_bridge
acts as a Schmitt trigger.

Fix two bugs in the "let" command:

"let plot.vec = ..." fails when creating a new vector;
if the new vector does not exist, "let" may modify a "const" value.
It is likely that existing scripts rely on the second one,
so variable "sanelet" must be set to enable the fix.
