receiver cascade simulation tool

we design receiver block diagram but how can we see the dynamic range,noise figure and RF input levels so please help for receiver simulation tool.

Agilent has a free tool to estimate those specs.
It's AppCAD that is available to download at Avago's website..There might be other free simulators on the web..
If you have money, Systemview or ADS are good professional simulators.
Matlab/Simulink is another alternative..
You got choices...

SysCal has some free version, you can download and try.

Thank u very much
