Cadence Design Professional stuff
for people making their living with IC design, >100k$.Only good with a
fast UNIX workstation. SpectreRF is capable of some limited non-linear
Mentor Graphics Professional stuff for people making their living with IC design, >100k$. Like Cadence, only good with the most expensive workstation, since the software is sometimes more expensive than the designer using it. Moreover, Mentor is not so suitable for the Analog/RF IC designer.
Tanner Research (>10k$) Tspice and other tools (L-edit) for the IC designer.
SIMetrix -Newbury Technology- a 500$ Analog Spice simulator with schematic entry. It also features a full BASIC-like scripting language allowing the automation of multiple simulations and customized analysis of simulation results.
MyCAD MySpice, a ??k $ plain vanilla "analog mode" mode Spice.
Intusoft ICAP/4, a 2~4k $ mixed mode simulator with schematic entry.
OrCAD/Microsim Pspice, a multi k$ mixed mode simulator with schematic entry and PCB layout. Version 9 schematic entry (OrCAD) is a big step back.
Penzar Development Topspice (a 500$ excellent mixed mode simulator, smith-chart plotting is included !)
Electronics Workbench Multisim a 700~3k $ mixed mode simulator with a 700$ RF module for linear RF goodies like Smirth Charts with gain circles etc.
RF Design Tools
Chart Calculator: Useful for defining the specifications of RF filters.
Cascaded Block Analysis: Good tool for analyzing a cascade of blocks. Only runs on UNIX
ANADIGICS Receiver Model Tool: A demonstration tool for receiver block analysis. Adding or deleting blocks is not possible.
Spectrum Allocation Chart: At first glance it looks like a great chart, but it really doesn't give you much needed information.
RF Design Tools EDA vendor sites
Packard HP-ADS Market leader. Excellent multi multi k$ RF simulator.
Good for the system designer or the designer making PCB boards with soldered
components. clumsy for the IC designer.
APLAC Excellent University simulator from finland. Block level and schematic level are not fully integrated. Now commercial with the Nokia tool for schematic entry. Too bad that it is still a multi k$ tool.
Ansoft The Serenade Design Environment (from Compact Software), a multi k$ PC-based tool for RF designers.
AWR Stephen A. Maa$'s Microwave office, a 20k US$ package. 30 days demo available. Look and feel of HP-ADS.
