Modern designs need power - often lots of it at very low voltages. High power and low voltage means the impedance of the Power Delivery Network (PDN) needs to be very low. HyperLynx analyzes the behavior of your design's PCB at both DC and AC to ensure that components get the power they need, at the voltages they need, at the frequencies they need.
HyperLynx DC Drop analyzes steady-state current flow to ensure that components receive adequate voltage and that current in power planes and power vias doesn't exceed safe levels. Excess current density can overheat areas of the board and cause board failure.
HyperLynx Decoupling analysis ensures that transient demands for additional current caused by IC switching behavior will be reliably satisfied. Modern PDN's use a hierarchy of decoupling capacitance to service these demands; component values, routing and placement are critical. HyperLynx models the complete PDN structure to ensure that components will get the power they need to run at full speed.
