This item tracks the voltage and signal lines in the circuit, calculates the voltage
value of each net, and checks whether the all resistor connected to the net is within the
allowable voltage range.
Figure 1.
Component: Select
resistor component group to be checked.
Comp Value
Property: Enter the value of resistance or select the property which contain
the value of resistance.
Figure 2.
Net: Select net
group to which resistor components are connected.
Power Net: Select
power net group to which resistor components are connected.
Ground Net:
Select ground net group to which resistor components are connected.
Voh: Set the
output high voltage (Voh) of driver pin. You can set this by entering the
value directly or select the property name which contain voh value.
Vol: Set the
output low voltage (Vol) of driver pin. You can set this by entering the
value directly or select the property name which contain vol value.
Working Voltage
Check: Set the allowable working voltage of this component. You can set this
by entering the allowable value directly or select the property name which
contain allowable working voltage value. You can also assign tolerance of
this check.
Figure 3.
Power Dissipation
Check: Set the allowable power dissipation value of this component. You can
set this by entering the allowable value directly or select the property
name which contain allowable power dissipation value. You can also assign
tolerance of this check.

Stress Test Option
Stress Test Option: Set whether passive components are considered short or open when
navigating signals and power lines. Upon double-clicking the empty field, the
Stress Test Option dialog opens.
Figure 5.
Power Net Composite Section: In this section, we declare the component to be
processed short and the component to be opened during power trace navigation. Since
Stress Test is a DC level test, the capacitor is considered as open and inductor is
considered as short. And normally the resistor is considered as open, because the
current of power net is so big that the IR-Drop can’t be ignored. Since TR and FET
are used as switching components, they are regarded as short when voltage navigating.
Open Component:
Select the component group to be regarded as short when power trace
navigating.
Short Component:
Select the component group to be regarded as short when power trace
navigating.
Figure 6.
Signal Net Composite Section: In this section, we declare the component to be
processed short and the component to be opened during signal trace navigation. Since
Stress Test is a DC level test, the capacitor is considered as open and inductor is
considered as short. And normally the resistor is considered as short, because the
current of signal net is so small that the IR-Drop can be ignored.
Open Component:
Select the component group to be regarded as short when signal trace
navigating.
Short Component:
Select the component group to be regarded as short when signal trace
navigating.
Figure 7.
Short Pin Section: TR or FET is a device with three pins, so it needs information
about pins connected to each other during short processing.
By Pin Name:
Declare pin paring information as pin name. If there is more than one
condition, the separator “,” is used.
By Signal Name:
Declare pin paring information as signal name. If there is more than one
condition, the separator “,” is used.
