Square Wave Current Source (Tone 2): I_SQR2



This signal source is superseded and should be replaced with one of the following: AC_V for voltage sources, AC_I for current sources, or PORT_SRC for ports, with the Signal parameter set to this signal type.

The period for tone 1 sources is the inverse of the specified simulation frequency; see “Frequency Sweep Control” for details.


Name Description Unit Type Default
ID Current source ID Text V1
AMP Signal magnitude Current 0 mA
F Signal frequency Frequency 0 GHz
TR Rise time Time 0 ns
TF Fall time Time 0 ns
TD Time delay Time 0 ns
WINDOW Window type   DEFAULT[1]
Offset Waveform offset (does not affect DC) Current 0
DCVal DC value (used for DC analysis) Current 0

[1] Window type options are none (NONE), Lanczos (DEFAULT, ref [1]), Triangular (TRIANG), Hanning (HANN), Hamming (HAMM), Blackman (BLACK). See I_PLS for additional details on the WINDOW parameter.

NOTE: Cadence® AWR® simulators add some series resistance to this element during simulation. This may affect results if injecting current into a large resistance. To change the value of the resistance, choose Options > Default Circuit Options to display the Circuit Options dialog box, then click the AWR Sim tab and under Convergence Aids specify the Series source resistance.


This element does not have an assigned layout cell. You can assign artwork cells to any element. See “Assigning Artwork Cells to Layout of Schematic Elements” for details.
