Schematic review today
A process that combines DRC run and checks with a manual review of the schematic
A very labor intensive work with very problematic result due to high human error chances
Complex to implement all required rules to comply to company specs
4
When the fiXtress Schematic Review is used
Used directly during and at the end of the design process
Used after a regular DRC is used to prevent duplicated errors.
Before an automated stress analysis is done
5
fiXtress solution: automated schematic review
fiXtress component libraries contain a component models that provides better insight
fiXtress Schematic review checks a wide rang of rules to find a deeper level of errors that up until today were mainly manual
Allows for customization and for creation of new rules for company specs
6
fiXtress Schematic Review concept
BOM & Netlist imported from different CAD software
Project rules and common rules are chosen to comply to the company and design specs
Run the chosen rules and screen the relevant errors into the report
Rerun as needed
7
Core set of fiXtress schematic review common rules
8
Each Group is actually a family of rules that produce error massages according to the cause of the described principle
Schematic Review rule selection
9
Chose the relevant rules for your project and company specs
The schematic review checks for rule compliance for the project
Press Copy to project to use selected rules
Error check and error report
10
Press the verify button to run the selected checks
Check the relevant errors and add them to the report

The SDA bus requires pull up resistor per the data sheet.The pull up resistors are set as “LAB” therefore were not populated
Schematic Error Example:connectivity verification

INT/ pin is an Open Drain pin which the data sheet requires pull-up resistor

device through the SDA terminal. Notice that if the I2C-bus common pull-up resistors havenot been installed as required for I2C-bus, then an external pull-up resistor, about 10 kOhm,is needed for each of these two terminals.
Schematic Error Example:connectivity verification
The pull up resistor value is not within the required by the manufacturer
14
Schematic Error Example: Common rule
The required decoupling capacitor is 10uF in the design the decoupling is 0.1uF
Pin 3 is not connected pin but there is a connection to 5 volt
