Method detail#

CrossTalkTime.add_single_ended_net(name: str, driver_rise_time: float | str = 5.0, voltage: float | str = 10, driver_impedance: float | str = 5.0, termination_impedance: float | str = 5.0) → bool#

Add single ended net.

Parameters:
namestr

Net name.

driver_rise_timefloat or str, optional

Driver rise time value. The default is 5.0.

voltagefloat or str, optional

Voltage value. The default is 10.

driver_impedancefloat or str, optional

Driver impedance value. The default is 5.0.

termination_impedancefloat or str, optional

Termination impedance value. The default is 5.0.

Returns:
bool

True if the net was added successfully, False otherwise.

Examples

>>> xtalk = CrossTalkTime(pedb)
>>> xtalk.add_single_ended_net("DDR_DQ0", driver_rise_time=2.0, voltage=1.2)
True
CrossTalkTime.add_driver_pins(name: str, ref_des: str, rise_time: str = '100ps', voltage: float = 1.0, impedance: float = 50.0) → None#
