calcVal() works fine over corners but not when variable swept

I am using calcVal() with evaltype = "corners" to do some maths between 2 corners and it works fine until a variable is swept. I was expecting a calcVal result for each sweep but get eval err instead. I dont want to use "all" as i want individual results per sweep step. Is the simulator converting the series of corners when swept as a wave so i need to modify the expression?

What's the expression and which version are you using?

Hi Andrew,

(100 * ((calcVal("NF@Fgmax" "LNA_LB" ?cornerName "C16_wcc") - calcVal("NF@Fgmax" "LNA_LB" ?cornerName "C0_typ")) / calcVal("NF@Fgmax" "LNA_LB" ?cornerName "C0_typ")))

L - apologies, been rather busy of late and so have got very behind answering questions on the forums.

I tried your expression (adapted slightly for a different test bench) and it worked fine with sweeps in ISR32. I checked again in ISR19 and it still worked OK.

The best bet is to contact customer support. Alternatively if you want to come along to the CadenceCONNECT event in Bracknell on 6th June, we could look at it then ;-)
