(3 ) EDA simulation calculation application

The simulation calculation of aerospace electronic control system mainly involves: circuit simulation of electronic and electrical equipment and control systems in aerospace systems, and electromagnetic field simulation calculation applications. On the other hand, the electromagnetic field simulation of compatibility and anti-interference of equipment and systems in complex electromagnetic environment, the following are mainly for the latest high-end graphics workstation configuration specifications for these two types of applications.    

3.1 Electronic circuit system verification and simulation workstation
This type of application mainly involves the verification and simulation calculation of electronic circuits and electrical equipment in various aerospace electronic equipment.

For medium and large-scale applications with extremely high frequency and a certain number of cores for parallel computing requirements, the entire machine is in the state of ultra-high frequency , single-core computing and multi-core parallel computing, GPU supercomputing, high-speed reading and writing ensure the perfect operation of each link of the software, thereby Dramatically reduce computation or processing time.

3.2 Simulation of microwave electromagnetic field

The electromagnetic simulation problems of aviation equipment mainly include electromagnetic interaction between antenna and aircraft carrier, avionics EMI , electronic link budget analysis, radar signal characteristic analysis, aircraft RCS and so on. Using numerical methods to simulate the electromagnetic compatibility problem and analyze the calculation results, the electromagnetic compatibility of the equipment can be effectively predicted and evaluated, and a reliable theoretical basis for the electromagnetic compatibility design of the equipment can be provided.

Typical algorithms: method of moments, finite difference time domain method, finite element method

Computing Features:

(1) The method of moments (MOM) transforms the integral equation into a difference equation, or transforms the integral in the integral equation into a finite summation, thereby establishing an algebraic equation system, so its main workload is to solve the algebraic equation system with a computer. Therefore, in the process of solving algebraic equations by the method of moments, the size of the matrix involves the amount of memory occupied, which greatly affects the speed of the calculation. How to reduce the amount of matrix storage as much as possible becomes an accelerated method of moments calculation key.

 

( 2 ) Finite Difference Time Domain ( FDTD ) is a numerical algorithm based on the time domain electromagnetic field differential equation, which directly approximates the Maxwell curl equation in the time domain with the central difference of second-order precision, thereby transforming the solution of the time domain differential equation into The iterative solution of the difference equation, the multi-core parallel computing speedup ratio is good, and the requirements for the computer memory capacity are low.

 

( 3 ) Finite Element Method ( FEM ) is a numerical technique for obtaining approximate solutions of boundary value problems of partial differential equations. It uses the variational method to make the error function reach the minimum value and generate a stable solution. The amount of calculation and memory capacity is huge, and the temporary files are frequently written back to the hard disk.
