could I find FM source with rail-to rail output?

Dear Sir:
I need help to find a voltage controlled source
whose frequency can be adjusted by <VTUNE>
with rail-to rail (square wave) output.
Or say it is a VCO with square-wave output.
in ADE environment.
Thanks in advance.

Try the vco in ahdlLib supplied by cadence. It is a veriloga view. you modify the code for you own needs, or stick an inverter/limiter on the output to get your square wave.

There are also Verilog-A VCO models at
