Si Software Simulation

1. If you do not know the basic theory of Si, do not blindly pursue the use of software. The purpose of simulation is to understand the cause of the problem and avoid the problem.
2. If e can, help Doc will be more conducive to software learning (do not read doc as a textbook, but as a tool book to find what we need

3. Typical SI simulation software. It is strongly recommended that new users learn hyperlynx, which is easy to use and will not be confused by complicated simulation parameter settings. Xilinx, Altera, micron, IDT and other manufacturers are using hyperlynx.

4. The sq function is relatively powerful, but it also means that the workload you need to perform simulation is increased. Set, set, and then set.
5. hyperlynx is similar to sq. I have a deep understanding of one of the software, and the other will not obscure you.
6. Currently, we are also using HSPICE for SI simulation. xdjm is a valuable time. We recommend that you do not write the SP file (netlist), which will drive you crazy.
7. Ads is more used in the RF and microwave fields (the difference between RF and MW)
8. siwave pi is really good.
9. The quantum-Si of sisoft is quite good in terms of functions, especially in timing analysis. It is attractive, but it has not been added to version D yet.
10. icx/Tau, which has eight functions wrong. I have never seen Si software operate such a complicated one. After two days of exploration, I finally gave up. To work with dition, I can use BRD to export icx files, the icx interface is available only in spb15.7 or later versions. Icx/Tau Help Doc is good and has many basic theories

11. Do not think that any software is intended for use. It is right to honestly lay down the basic theory.

Indeed, the current division of labor is getting finer and finer, so it is impossible for layout to conduct in-depth research on Si and simulation. However, the SI theory related to layout still needs to be mastered. There is also a way to learn Si. First of all, if you have a good analog circuit, those theories will be easy to understand. In my personal opinion, analog circuits are the root of Si, and the world is simulation. When it comes to simulation, there are a lot of simulation tools today. The sq and hyperlynx of low frequency segments (below GHz) are mostly used, but the timing is lacking, and the qsi timing can also be used, the high-frequency section of the heat map is used in many ways, and the precision is also high. Pi can use siwave, speed2000, and so on. For three-dimensional modeling, we should use it, like ads, it is very difficult for you to understand the electromagnetic field theory. The method of using the software is actually very simple. The key is whether you can understand the processing process and output of the software. In the end, it cannot be too impetuous, if you want to learn everything, you cannot learn anything.
