DDT(x) time derivative of x which is applicable to transient analysis only Note: In waveform analysis, this function is D(x). SDT(x) time integral of x which is applicable to transient analysis only Note: In waveform analysis, this function is S(x). TABLE(x,x 1 ,y 1 ,...) y value as a function of x where x n ,y n point pairs are plotted and connected by straight lines MIN(x,y) minimum of x and y MAX(x,y) maximum of x and y LIMIT(x,min,max) min if x < min max if x > max else x SGN(x) +1 if x > 0 0 if x = 0 -1 if x < 0 STP(x) 1 if x >= 0 0 if x < 0 which is used to suppress a value until a given amount of time has passed Example: {v(1)*STP(TIME-10ns)} gives a value of 0.0 until 10 nsec has elapsed, then gives v(1). Table 3-4 Functions in arithmetic expressions, continued This function... Means this...
