PCB signal and power layer estimation is not an exact science, but over the past 40 years, several estimation algorithms have been published and become well-known. Sierra Circuits’ Signal and Power Layer Estimator uses these algorithms to calculate the minimum number of signal and power layers required to accomplish all the interconnections in a PCB layout.
We have developed this tool to assist you in the design and development stages of a circuit board. The number of signal and power layers required determines the overall time and the manufacturing cost. Knowing the right number of required signal/power layers eases the design process.
There is no particular rule that describes the number of signal layers required for a particular circuit board. It depends on the type, length, width, and shape of the board. It also depends on the number of component pins, trace width and spacing, via pad diameter, keep out areas, etc. Our tool uses the values of these quantities and specifies the number of signal and power layers, rounded to the nearest integer.
The Signal and Power Layer Estimator has two sections – input and results. You have to enter all the parameters mentioned in the input section. An illustration of a board with all the input parameters defined is placed on the home page of the calculator.
Before providing the values, select the unit in which the calculation is to be carried out. By default, the unit is set to mils. Other available options are inches, millimeters, micrometers, and centimeters.
Enter the following required values in the input section:
Next, hit calculate in the results tab. The tool will display the following results in red at the bottom:
Along with this, the following values are also obtained:
We offer an easy-to-use Signal and Power Layer Estimator that will eliminate your complicated design delays. With the help of this tool, you will be able to understand the required number of signal and power layers in a go. Keep all the necessary input parameters handy and get a hassle-free estimation in no time.
