Cadence is a tool vendor, the simulator is Spectre. There is an ideal switch SW in SPICE and Spectre And there is a manual named Spectre Circuit Simulator Reference. Another option is a behavioral voltage source (B component).is there such a switch in cadence?
You could consider using poly sources (vcvs) to create Vdd and the "switching input", a (say) 0-1V ramp at one terminal pair for the time varying aspect, a V=3.3 source multipled by the ramp is your rising Vdd and do the same scaling for a 0-Vdd pulse source through a second poly vcvs.
Or you could go grab yourself a veriloga (or transistor level) inverter cell and string a couple together, powered off Vdd and passing the logic signal.
does anyone have an idea which component in cadence lib would achieve that?
What do you want to mean by”Cadence lib” ?i have in cadence a library called cadencelib which i'm using for simulating ideal components
You can not understand tools which you use at all.That's the library i'm using
You can not understand tools which you use at all.
They are just symbol’s library which are supplied with Cadence dfII.
You can see available all Spectre primitives by “spectre -h”.
Some of Spectre primitives are reflected as symbol in “analogLib” and “rfTlineLib”.
You can see Verilog-A models in “ahdlLib”, “bmslib”, “rfLib”, “pllLib” and “pllMMLib”.
However these are not useful for specific application.
Create custom signal source by Verilog-A.
The author is so unclear...
What I have understood, the point here is to have square wave with 50MHz frequency, and levels between ground and vdd, while vdd is defined by another vdc source. This vdd is a variable. If so, use the same variable in vpulse component as second voltage.
If my understanding is incorrect, please explain your issue clearly.
BTW. VerilogA module or any more complicated stuff is not needed IMO
No. Ideal switch means SPICE SW component is controlled by a pulsed voltage source, it's only use is in transient simulation.the same applies for the ideal switch it can't be switched in transient response

Similarly you can use behavioral voltage source, e.g. output voltage = product of voltage a and voltage b
