Special DC and Transient Analysis

Hello everyone,

1) I have some simple queries regarding the aforementioned analysis. In the following discussion:

# Running AC analysis after certain time of transient analysis

we find the guy saying that DC analysis at a paritcular instant of transience is possible. How is it possible? and how do we do this in Cadence 6 setup.

2) I have 50 Monte carlo simulations for tarnsient analysis from 0 to 300us for a nodal voltage in some design. The nominal value for the nodal voltage is 40mV. I get variations from 36mV to 48mV. But the 50 plots vary wrt time due to some switching phenomena going on in the circuit. Therefore I want a histogram at only 55us which must show me the no of occuracne on x axis and the range of values on y axis. How can I get such a histogram at 55us in Cadence 6 environment.

Re: Special DC and Transient Analysis
 On the transient options form, there's a field labelled infotimes . Specify the times you want to save the operating point at.I think you've got your x and y back to front, but in ADE XL you'd have an output expression such as value(VT("/theNodeName") 55u) or value(v("/theNodeName" ?result 'tran) 55u) - then you'll get a histogram for that.Regards,Andrew.
