Where are engineers going to get those parameters with sufficient accuracy? Estimates? Yes, but how many can cross-section a board? So our biggest challenge as an industry is working together to provide engineers with the modeling data they need.
The solvers are just processing Maxwell’s equations, but they need input parameters that allow that level of accuracy.įor example: surface roughness affects loss, as does loss tangent and stackup thicknesses have to be as-manufactured. Well, to do that you need to be that accurate on all of the input parameters for your solvers. I remember a numerical equivalent that someone mentioned awhile back: “one picosecond is to a second as a second is to 31,000 years,” and we are trying to be picosecond accurate to verify these new interconnects. SIJ: Within the competitive landscape of the industry, what are the greatest challenges your company faces technically?ĭave Kohlmeier: There are many challenges, but modeling data is probably the biggest. The 3d field solver version, aka Hyperlynx 2.224 Gb/s Per Lane: Options and Challenges Other than that - I'll add that Hyperlynx comes in 3 flavors In addition there is also "ADS" - or analog design studio (keysight), where you can do near field solves or make channel models of berr/eye based on physical constructs of board for serdes linesĪnd, there is also simbeor, which Altium is partially using,Īnd, a very basic one from "TOYO" which is called emistream There also used to be "speed 2000" which is what cadence now sells you to see air flow in an enclosure) I think you would need something else (e.g. Along with SI and PI, can we expect these tools to do some thermal analysis?ĪDS does some thermal analysis, but for real flow (e.g. Some other softwares are more difficult to use I am personally a Hyperlynx user, but it is not that easy to work. I do not really have a favorite one, I used to work in Hyperlynx and I liked that it was simple to use, Cadence now has some simulations directly in Allegro (it can be useful), ADS - depends what analysis, but some are super simple to setup (however e.g. Of course, you probably mean which I think is the best software, but I think you may get similar results - only the question is how complicated it will be to get the results.
To use the tool properly, it is very important to be able to talk to someone in the company directly.
The one where you can get the best support. Among them, which do you prefer for your board analysis? Do you want to add another tool to the list?
