  7. 7. VI HAR RESSOURCERNE … Schematic preparation – Edit properties on Nets and Comps – How – Select one or more nets/components – Ctrl+E to edit properties – Select Filter By to ’Cadence-Allegro’ – Net Properties – use Flat Nets – ’Min_line_width’ is the default width used during routing – ’Net_physical_type’ puts net into netclass for easier handling of width and via assignments – ’Net_spacing_type’ puts net into netclass for defining advanced spacing constraints – Netclass (spacing and physical type) definitions are needed for auto matchup towards board template – Component properties – ’Room’ used to group components for easier placement Constraints = Design Rules
  8. 8. VI HAR RESSOURCERNE … Spacing and physical rule matchup • Use the following Net_Physical_type names to get constraints as shown • Use the following Net_spacing_type names to get constraints as shown Net_Physical_Type Width Via type <None> 0.2mm via26 Power 0.5mm via40 AD 0.1mm via26 Constraint Sets in PCB Editor 01mm 0.1mm via26 02mm 0.2mm via26 05mm 0.5mm via40 Via names Size Hole Via40 1mm 0.6mm Via26 0.7mm 0.3mm via75 2mm 1mm Net_Spacing_Type <None> Power AD <None> 0.2mm 0.5mm 0.2mm Power 0.5mm 0.5mm AD 0.1mm Constraint Sets in PCB Editor L-L L-S V-S V-V V-P 01mm 0.1mm 0.1mm 0.1mm 0.1mm 0.1mm 02mm 0.2mm 0.2mm 0.2mm 0.2mm 0.2mm 05mm 0.5mm 0.5mm 0.5mm 0.5mm 0.5mm Legend Type Description L Line Track/cline P Pin Component pin S Shape Copper pour/area V Via • Individual Constraints (properties like Min_line_width) overrule above table per default • See animation slide for creating constraint sets and matchup as shown above

  12. 12. VI HAR RESSOURCERNE … Constraints • How – ’c’ for Constraint Manager – Excel like spreadsheet with constraint values – Preferred method – Create Constraint Sets (Csets) – In ”Physical/Spacing Constraint Set” section of constraint manager – Let Net and NetClasses reference these Csets – Use ”Referenced Physical/Spoacing CSet” column – Individual constraints can be set – Blue values denotes overrides – On net – Mouse over net, Right click, Property Edit
  13. 13. VI HAR RESSOURCERNE … Placement • Press ”p” for placement dialog – Filter components by room, net, refdes etc. – To place using coordinates click p-icon at the bottom • Most used Place Shortcuts – Rotate 90 degree (r) – Rotate 45 degree (R) – Rotate other angles – Set angle in options panel – Mirror (m) – Place by coordinate (x or y) – ’P’ for hidden placement dialog – Use to move placed components
  14. 14.

(point sign) or icon • In case of DRC errors – Get information using Mouse over DRC marker, right click, show element – Waive any DRC errors that are acceptable. – Mouse over, Right click, Waive DRC • Footprint library path check – Tools, Quick Reports, Symbol Library Path Report – Will show if all footprints are taken from company footprint library • Display Status – Press , (comma)
  17. 17. VI HAR RESSOURCERNE … Post processing – Double check Display, Status menu – Create drill legend (drawing) – Manufacture, NC, Drill customization – Click ’Autogenerate symbols’ for unique drill symbols to each drill type/size – Manufacture, NC, Drill Legend – Adjust settings to your need and press OK – Now place the legend on the PCB – Create drill files – Manufacture, NC, NC Drill – Check settings and press ’Drill’ – Create Route files (if slots are present) – Manufacture, NC, NC Route – Check settings and press ’Route’ – Ipc out – File, Export, IPC 356 and click export
