Hello,
I am a newbie to ADS and I want tutorials on that.
What is the difference between the following ADS products
ADS
SYSTEMVUE
GENESYS
EMPRO
VEE
GOLDENGATE
MOMENTUM
Does Agilent has any 3D EM solvers like HFSS/CST or is everything planar em simulators only.
Kindly clarify,
EMPro if a full 3D EM simulator, like HFSS. It uses the finite difference time domain method, as well as an FEM based method. It is based on Remcom's XFdtd. An engineer from Remcom told me EMPro is based on an older version of their solver. When I asked Agilent about this, they conceeded it was true. If you look at the interface for XFdtd and EMPro, you will see they look almost identical. I don't know if Agilent are developing the core solver themself, or just buying updates from Remcom.
EMPro integrates with ADS, but is also a standalone product.
The EMPro documentation and tutorial are on the Agilent web site, but I believe you need a login to get them. I've found the documentation a bit poor in places. In fact, I sent a list a the issues to Agilent. Some of the diagrams can't be read as the resolution is too low. I've also recently found one of the screenshot in the documentation quite different from what you actually get with the latest EMPro. As such, it is a bit confusing what one is supposed to enter in some of the boxes.
Be aware EMPro uses flexlm - with all the problems that piece of **** brings. I recall a discussion once at one of the regular meetings about the Solaris operating system, which was developed by Sun, but is now owned by Oracle. One former Sun employee said Sun stopped using flexlm to protect their software, as a very high percentage of the support requests were related to licensing issues.
Another ex Sun employee said he thought flexlm was good, as it taught Solaris system administrators about LD_PRELOAD. Basically, too many people got fed up with flexlm stopping their legal software from working, that they spoofed their system so flexlm worked. Another guy said his company released software that was supposidly "protected" by flexlm. He said within two weeks someone had cracked the encryption.
