  2. 2. BQR Profile  Founded in Israel at 1989 as a consulting company in the field of reliability and maintenance engineering  More then 2,000 projects and over 120 customers  All our software solutions developed based on customers needs and thousands of successful projects for RAMS &ILS  Today the main business of BQR is to develop and sell software for the EDA market 2 BQR Confidential Information

  4. 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 4
  5. 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 5
  6. 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 6
  7. 7. 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
  8. 8. 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
  9. 9. 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
  10. 10. 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
  11. 11. 11 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
  12. 12. 12 INT/ pin is an Open Drain pin which the data sheet requires pull-up resistor Schematic Error Example: connectivity verification
  13. 13. 13 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
  14. 14. 14 Schematic Error Example: Common rule The required decoupling capacitor is 10uF in the design the decoupling is 0.1uF
