Extended Simulation Functions
_simu_set_cond
Task function category: Simulation Flow-Control Functions
Sets a stop condition.
Usage
_simu_set_cond("condition")
Arguments
• "condition"
Stop condition.
Description
The condition can refer to the simulation time value (time), the real time (elapsed_s, elapsed_n,
elapsed_h), the simulation progress (progress), voltages or currents and labels of extracts using
the transient extraction language (but the corresponding .PLOT commands must have been
specified in the netlist and the extract label must be enclosed inside the meas function).
Examples
Notes:
_simu_set_cond("v(2) > 1.5")
_simu_set_cond("(time > 500n) || (elapsed_m >= 20)")
/* If a '.extract tran label=cross1 tcross(v(2),vth=1)' is contained in
the netlist:*/
_simu_set_cond("meas(cross1) > 0")
• Only one condition can be active at a time. A call to _simu_set_cond will delete the
previous conditions. However, multiple conditions can be combined into one condition
using the boolean operators || and &&.
• If you want to use more complex expressions, it is advised to add parentheses around the
different parts composing the expressions. Most of the time, it will help prevent syntax
errors.
The result structure returned by the _simu_run function has a field named simu_stop. It can be
used to know if the simulation has stopped because the condition set with the _simu_set_cond
function has been met or if it has stopped because the simulation has ended without reaching the
condition. If the condition is met, then the _simu_stop attribute will be set to 1. If the simulation
has ended, it is set to -1. If the simulation stopped because of the mode attribute of the
_simu_run function (for example if mode="for 2n" and that the simulator completed the
simulation of this time period), then it is set to 0.
