| + | ====== "alarm" command ====== | ||
| + | |||
| + | ===== Purpose ===== | ||
| + | |||
| + | Select points in the circuit to check against user defined limits. | ||
| + | |||
| + | ===== Syntax ===== | ||
| + | alarm | ||
| + | alarm mode points ... ... | ||
| + | alarm mode + points ... ... | ||
| + | alarm mode - points ... ... | ||
| + | alarm mode clear | ||
| + | |||
| + | ===== Comments ===== | ||
| + | |||
| + | 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) | ||
| + | parameter(index)(limits) | ||
| + | |||
| + | Some require a dummy index. | ||
| + | |||
| + | For more information on the data available see the print command. | ||
| + | |||
| + | 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 deleting. | ||
| + | |||
| + | ===== Examples ===== | ||
| + | |||
| + | 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. | ||
| + | alarm | ||
| + | List all the probes for all modes. | ||
| + | alarm dc | ||
| + | Display the DC alarm list. | ||
| + | alarm ac clear | ||
| + | Clear the AC list. | ||
