4. 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

5. 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

6. 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

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

The SDA bus requires
pull up resistor per the
data sheet.
The pull up resistors are
set as “LAB” therefore
were not populated

device through the SDA terminal. Notice that if the I2C-bus common pull-up resistors have
not 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
