AUGUST 2019 I DESIGN007 MAGAZINE 79 When a high-speed net crosses a split plane, it can create an impedance discontinuity on the signal trace, possibly leading to unwanted re- flections, radiation, and crosstalk. With the in- creased complexity and density of today's PCB designs, finding and reviewing all instances of a net crossing a split plane is a grueling man- ual process. Additionally, standard simulation tools do not typically check for those occur- rences. When the nets crossing gaps rule is run in DRC, it is easy to pinpoint exactly where all instances of these discontinuities may appear. After running a rule, designers can select the spreadsheet tab to display a list view of results Figure 3: When an instance of a rule violation is selected, the DRC tool will zoom to the location of that violation on the PCB design within the DRC window. Figure 4: The integrated DRC client is shown inside of the PCB layout tool. This can be used to easily run or rerun rules once PCB changes have been made.
