Extended Simulation Functions
_simu_set
Task function category: Netlist Modification Functions
When using the simulation flow-control functions, it is possible to modify some netlist
parameters between runs with the _simu_set function.
Usage
_simu_set("e", "device", ["W/L/AD/AS/PD/PS/NRD/NRS/AREA",] va1)
_simu_set("m", "model", "parameter", val1)
_simu_set("p", "parameter", val1)
Arguments
• _simu_set("e", "device", ["W/L/AD/AS/PD/PS/NRD/NRS/AREA",] va1)
This function can be used to modify the value of the device device. If necessary, the
parameter name must be specified.
• _simu_set("m", "model", "parameter", val1)
This function can be used to change the value of the parameter parameter of the model
model to val1.
• _simu_set("p", "parameter", val1)
This function can be used to change the value of the parameter parameter to the value val1.
Description
The value of its first argument must be either e, m, or p, and specifies the type of data to modify:
device, model, or parameter. Compared to the simulation function, the advantage of this flow is
that the simulator does not need to elaborate the netlist again, which would be costly if the
netlist is large.
Examples
Example 1:
w = _simu_set("e", "m16", "w", 4.8u)
Example 2:
Here is an example of finding the value of a parameter that will make the voltage of node 2
reach 1.5V before 10ns.
