EFREQ and GFREQ properties are defined as follows: The DELAY property increases the group delay of the frequency table by the specified amount. The delay term is particularly useful when an EFREQ or GFREQ device generates a non-causality warning message during a transient analysis. The warning message issues a delay value that can be assigned to the part's DELAY property for subsequent runs, without otherwise altering the table. The output of the device depends on the analysis being done. For DC and bias point, the output is simply the zero frequency magnitude times the value of EXPR. For AC analysis, EXPR is linearized around the bias point (similar to EVALUE and GVALUE parts). The output for each frequency is then the input times the gain of EXPR times the value of the table at that frequency. For transient analysis, the value of EXPR is evaluated at each time point. The output is then the EXPR value used for table lookup; defaults to V(%IN+, %IN-) if left blank. TABLE series of either (input frequency, magnitude, phase) triplets, or (input frequency, real part, imaginary part) triplets describing a complex value; defaults to (0,0,0) (1Meg,-10,90) if left blank. DELAY group delay increment; defaults to 0 if left blank. R_I table type; if left blank, the frequency table is interpreted in the (input frequency, magnitude, phase) format; if defined with any value (such as YES), the table is interpreted in the (input frequency, real part, imaginary part) format. MAGUNITS units for magnitude where the value can be DB (decibels) or MAG (raw magnitude); defaults to DB if left blank. PHASEUNITS units for phase where the value can be DEG (degrees) or RAD (radians); defaults to DEG if left blank.
