Power Rail Group Type Setup
To perform a Stress Test, the voltage value of each power and ground nets should be defined.
You can define voltage values of each power net and voltage of voltage divide logic.
- Power Net Group: Select power and ground net group to define voltage value.
- Net: Upon selecting this menu, all the selected power and ground nets are listed in the table below.
- Group: Upon selecting this menu, all the selected power and ground groups are listed in the table below.
- Find Voltage: Upon clicking this button, the voltage value of power and ground nets are displayed in the table below. To execute this menu, the table below must be setup first.
There are three types: Pin Property, Net Name, and Voltage types.
- Pin Property: You can assign power value using pin property of component which is connected to each power net.
- Net Name: If the power net name contains a voltage value information, you can assign power value using net name string of power net.
- Voltage(V): You can enter voltage value of power net.
Power Rail Group Setup
- Power Net Group: Select power and ground net group to define voltage value.
- Net: Upon selecting this menu, all the selected power and ground nets are listed in the table below.
- Group: Upon selecting this menu, all the selected power and ground groups are listed in the table below.
-
Select a Type and follow the steps for each:
- To assign power
value using pin property of component which is connected to each power
net, select Pin Property.
- Click the empty Property field to open the Select Pin Property dialog.
- Select the appropriate property, and then click OK.
- To assign power
value using net name string of power net, select Net
Name
- Enter the
voltage separator in the Net Name Filter field.Note: The voltage separator means that the character used to distinguish the decimal point of voltage. Ex: VCC1P8 => the voltage separator is P Ex: VCC1.8 => the voltage separator is “.” In this case, enter “.,P” as a voltage separator.
- Enter the
voltage separator in the Net Name Filter field.
- To enter your own
voltage value, select Voltage(V).
- Enter the voltage value directly in the Voltage(V) filed.
- To assign power
value using pin property of component which is connected to each power
net, select Pin Property.
-
Find Voltage: Upon clicking this button, the voltage
value of power and ground nets are displayed in the table below.
Voltage Divide Logic
You can find out the exact voltage value of voltage divide logic.
- Upon clicking Voltage Divide Logic, the Voltage Divide dialog opens.
-
Voltage Divide Component Section: In this step, we set up the component list
used for voltage divide logic and property in which the resistance value is
declared.
-
Power Composite Component Section: In this step, we declare the component to be
processed short and the component to be opened during power trace
navigation.
Note: Since Stress Test is a DC level test, the capacitor is considered as open and inductor is considered as short. Transistor or FET is assumed to be turned on and treated as either short or considering turn-on voltage. And TR or FET is a device with three pins, so it needs information about pins connected to each other during short processing.
- Short Component: Select the component group to be processed short during power trace navigation.
- Open Component: Select the component group to be processed open during power trace navigation.
-
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.
-
Consider Turn-on Voltage-Base Power Section: In this step, we declare the base
power net to start navigation, and declare the power component used for power
logic.
-
Consider Turn-on Voltage-Component Section:
-
Turn-on Voltage Section: In this step, we declare the turn-voltage of each
component group to be used during power navigation.
-
Show Voltage Divide Data & Voltage Assigned Data Section: In this step, you
can review the voltage of voltage divide logic.
