When performing design and development in the RF and microwave range, it is critical to have the correct software tools for simulation and modeling of circuits and systems BEFORE you start the circuit board layout process. A little time simulating with the proper tools can save many times that amount of time in test and debug, and may even save a circuit board re-design, since at RF and microwave frequencies, everything that goes into the design and layout matters, and simulation can often identifiy problems early in the design process. It can also be used to troubleshoot designs that are not working as they should. The software that Aerospace Consulting uses are the following:
And, speaking of software, Aerospace Consulting owns the following software packages:
Agilent Genesys, with all of its modules including Spectrasys, Momentum GXF, Harbec, Cayenne, and all of the various synthesis modules for filter, matching, oscillator, and pll design. These tools are for linear and non-linear RF, microwave, and analog circuit and system design and develop. The Momentum GXF module is for Electromagnetic (EM) analysis and antenna simulation. It is especially useful for designing microstrip patch antennas and antenna arrays, as well as other planar antennas and structures. Aerospace Consulting has been a beta tester for Genesys for a while.
Modelithics complete library for Genesys - This software provides highly accurate, substrate and pad-pattern scalable models for many families of capacitors, resistors, inductors, transistors, diodes, and other devices. With these models, the simulation results are virtually identical to the measured results on an actual circuit board since the models take into account the various stray aspects of real components, including the characteristics of the pads and the circuit board material.
Agilent SystemVue - This is an extremely powerful system simulator which can not only perform detailed simulations on complex communications systems, but it can also generate C and C++ code for integration into various DSP projects. Aerospce Consulting has also been a beta tester for SystemVue for a while.
IntuSoft Intuspice - This is a very powerful Spice simulator
Singula - This is another Electromagnetic analysis package. It is a 3D full wave high frequency solver.
Chronos - This is a very powerful full 3D Electromagnetic analysis package. It can simulate any arbitrary 3D structure. It is very similar to HFSS and CST Microwave Studio. It includes both a FDTD (Finite Difference Time Domain) solver and a MoM (Method of Moments) solver.
Altium Designer - This is our preferred software for circuit board layout. It can also be used for FPGA development, along with the Altium Nanoboard, which Aerospace Consulting also owns.
SolidWorks - This is a very powerful 3D cad package for mechanical design and packaging. It also integrates with Chronos to expedite the design of 3D structures to be analyzed in the Chronos 3D EM simulator
PCAD - Although we don't use it much after acquiring the Altium Designer software, we do have PCAD for circuit board layout if a client prefers that platform.
Matlab - This is a powerful, general purpose mathematics tool for calculation and graphing.
Mathematica - This is another powerful math tool
Mathcad - This is another powerful math tool
While Aerospace Consulting does not currently own the following software pacakges, they have been used on various projects and can be used on future projects by leasing them for a specific job.
Ansys HFSS - A very powerful 3D FDTD (Finite Difference Time Domain) EM (Electromatic) simulator that is very similar to Chronos and Singula which Aerospace Consulting does own.
CST Microwave Studio - Another very powerful 3D EM (Electromagnetic) simulator that is very similar to Chronos and Singula which Aerospace Consulting does own.
AWR Microwave Office - A very powerful RF and microwave linear and non-linear simulator. It also includes an EM (Electromagnetic) simulator. It is very similar to Aglient Genesys, which Aerospace Consulting does own.
Agilent ADS - A very powerful RF and microwave linear and non-linear simulator. It also includes an EM (Electromagnetic) simulator. It is very similar to Agilent Genesys, which Aerospace Consulting does own.
Aerospace Consulting also has a small machine shop for building test boxes and fixtures out of aluminum and brass.
Almost every company and department finds itself, occassionally, behind schedule on projects, or with more work than the staff and facilities can handle. Or, they find themselves with a new design that is just not working as expected. That is the time to call Aerospace Consulting. No matter how good your people are, it is always a good idea to have your design reviewed by someone from outside your organization, with no pre-conceived ideas about how your circuit or system should be designed, and no biases toward doing things in the way that your department or company has done them before. It may very well be that your design is sound, and there are no hidden flaws that your people missed because they were simply too involved with the project and the design to notice them, but it is always nice to have that second opinion. And, if you are building up the boards, and run into problems, that is a good time to call Aerospace Consulting. With years of experience in troubleshooting other people's designs, both through long years of experience on the bench, and with extensive use of simulation to locate design problems, Ed Troy is uniquely positioned to quickly get your new product up to expectations. After all, reviewing your own design is much like proofreading your own writing-- it is an almost impossible task. I never go to a client's facility to troubleshoot a design without my trusty computer and simulation software. I am amazed at how few engineers use simulation tools to debug a design. Now, most of us use them to perform the original design, but those same tools are invaluable as a debugging tool!
