There are also two ways of laying, manual and automatic.PowerPCB provides powerful manual laying, including automatic extrusion, online design rule check (DRC), specctra's cabling engine is responsible for automatic cabling. The two methods are usually used in conjunction with each other. The usual steps are manual - automatic - manual.
1.1 manual laying
1. Before automatic laying line, manually lay out some important networks, such as high-frequency clock, main power supply, etc., which often have special requirements on tracking distance, line width, line spacing and shielding, etc.; Other special packages, such as BGA, automatic laying is difficult to do, regularly and manual laying is required.
2. After automatic laying, PCB tracks shall be adjusted by manual laying.
1.2 automatic laying
After manual laying is finished, the rest network is handed over to automatic laying device. Select tools-> SPECCTRA, start the interface of SPECCTRA cabling, set the DO file, press Continue to start SPECCTRA cabling automatically, if the routing pass rate is 100, then manually adjust the tracking.If it is less than 100, it indicates that there is some problem for the layout or manual laying, so need to adjust the layout or manual laying until all the tracking is completed.
1.3 matters needing attention
A. Thicken the power line and ground line as much as possible;
B. Decoupling capacitor shall be directly connected with VCC as far as possible;
C. When setting the DO file of Specctra, first add the Protect all wires command to protect the manual wiring from rewiring by automatic wiring device;
D. If there is a mixed power layer, this layer should be defined as Split/mixed Plane. Break it up before wiring. After wiring, Pour Manager's Plane Connect is used to coat copper.
E. Set all device Pins to thermal soldering pins by setting Filter as Pins, selecting all pins, modifying properties and checking before Thermal option;
F. Turn DRC option on when routing manually and use Dynamic Route.
