Need to make calculations for resistance, capacitance, inductance, propagation delay, and line width calculated for a specific impedance requirement, for each net? 

Now you can!

CAD Design Software's High Speed software feature makes electrical calculations based on information in the PCB layout. The following calculations may be made within CAD Design Software for each net: resistance, capacitance, inductance, propagation delay, and line width calculated for a specific impedance requirement. It also performs voltage drop calculations on each branch of a power net based on the current load at each node taking the estimated temperature of each layer into account. High-speed rules set in the schematic and written into the netlist may be edited before they are read into the EPD-Allegro PCB Router Interface. 

High-speed rules in the schematic database, write the CAD Design Software netlist, feed it into CAD Design layout software, set or reset in CAD Design layout software and feed seamlessly into the Cadence Allegro autorouter. Rules set by the engineer in the schematic will automatically drive CAD Design layout software or the Cadence Allegro autorouter. Rules set in the Schematic or CAD Design layout software for direct feed into Cadence Allegro include maximum crosstalk, maximum length, minimum length, maximum parallel length, maximum stub length, Starburst, Daisychain and width. Rules calculated in CAD Design Software’s High Speed and fed directly into the Cadence Allegro autorouter include width for specific nets and layers calculated for impedance requirements.

Key Features Include:

1. Resistance, Inductance, Capacitance and Delay on each net.
    

2. Voltage drop of each branch of a power net - taking the temperature of each conductive layer into account.
    

3. Line width for a specific impedance of micro-strip.
    

4. Sums all thicknesses to get total board thickness.
    

5. Delay on a net - taking propagation speed of different layers and via distance into account.
    

6. Feeds data to the PCBStackup command which generates board cross sections for fabrication drawings.

• Control substrate, conductor and mask material types and thicknesses.

• Line width for a specific impedance of micro-strip.

• Built in material library.

• Voltage drop of each branch of a power net - taking the temperature of each conductive layer into account.
