2.6 ALARM command
alarm mode points ... ...
alarm mode + points ... ...
alarm mode - points ... ...
alarm mode clear
Select points in the circuit to check against user defined limits.
The `alarm' command selects points in the circuit to check
against limits. There is no output unless the limits are exceeded.
If the limits are exceeded a the value is printed.
There are separate lists of probe points for each type of analysis.
To list the points, use the bare command `alarm'.
Syntax for each point is parameter(node)(limits), parameter(componentlabel)(limits), or parameter(index)(limits). Some require a dummy index.
For more information on the data available see the print
You can add to or delete from an existing list by prefixing with
+ or -. alarm ac + v(3) adds v(3) to the existing
set of AC probes. alarm ac - q(c5) removes q(c5) from the
list. You can use the wildcard characters * and ? when
- alarm ac vm(12)(0,5) vm(13)(-5,5)
- Check magnitude of
the voltage at node 12 against a range of 0 to 5, and node 13
against a range of -5 to 5 for AC analysis. Print a warning when
the limits are exceeded.
- alarm op id(m*)(-100n,100n)
- Check current in all mosfets.
In op analysis, print a warning for any that are outside the range of
-100 to +100 nanoamps. The range goes both positive and negative so
it is valid for both N and P channel fets.
- alarm tran v(r83)(0,5) p(r83)(0,1u)
- Check the voltage
and power of R83 in the next transient analysis. The voltage
range is 0 to 5. The power range is 0 to 1 microwatt. Print a
warning when the range is exceeded.
- List all the probes for all modes.
- alarm dc
- Display the DC alarm list.
- alarm ac clear
- Clear the AC list.
