Working with IDF Best Practices: Working with IDF October 2019 4 Product Version 17.4-2019 © 1999-2019 All Rights Reserved. Figures 1-1 and 1-2 show the example flow. Note that this deviation of the suggested flow may result in additional work for the mechanical engineer if the resulting blocks of components have to be replaced with Pro/ENGINEER models and parts. In this case, it is recommended that you use the ecad_hint.map file to ensure proper part reference and translation. The coordinate systems must match between the Allegro PCB Editor footprint and the part model in Pro/ENGINEER. See Component Placement on page 10 for additional information. 3. Imports the schematic or netlist into Allegro PCB Editor. 4. Imports the IDF file. 5. Places all the components using Quick Place; exports the file. 6. 7. Imports the IDF file into the board assembly. This results in all parts being aligned around the board edges. The mechanical engineer now can replace the part blocks with existing Pro/ENGINEER models or just place the critical components. 8. Analyzes the board and assists the mechanical engineer in placing mechanical critical components. 9. Places critical components. 10. Exports the IDF file. 11. Imports the IDF file; places and routes, simulates and so on. 12. Imports the IDF file with all components placed. 13. Exports the IDF file when placement is final. 14. Performs final validation.
