HAC Express is a model simulation development environment based on FPGA, which focuses on high-precision modeling and ultra-high-speed real-time simulation, which makes up for the deficiency that the traditional simulation tool platform can not carry out nanosecond simulation.

Since its launch, HAC series has experienced considerable development and profound application accumulation from v1.0, v2.0, v3.0. Today, in order to meet the increasingly complex use scenarios, more massive Istroke O requirements, higher speed simulation beats, and more convenient modeling operations, Runke General track Electronics Division adheres to the purpose of "value innovation, customer service" and solemnly launches a new generation product-HAC Express.

As a new generation of high-speed simulation environment, HAC Express simulation tools software and HiFlex series hardware not only continuously improve the nanosecond simulation performance, but also enhance the data interaction bandwidth to Gbps level, but also provide a wide variety of IO interfaces and their expansion modules, which can meet the application needs of users of different sizes and complex scenarios. It really realizes the user demand of "using one device to simulate a whole set of system".

Moreover, HAC Express can be seamlessly integrated with HiGale simulation system, and can support complete dynamic code generation, simulation and target environment execution functions. HiGale simulation system can not only build simulation models through Matlab / Simulink modules, but also be compatible with a variety of professional offline simulation software (such as Dymola, AMESim, SimScape, SIMPack, etc.), and with high-performance processors and a variety of analog, digital, communication, and track professional application boards to achieve rapid prototyping and efficient iterative development. Now, after cooperating with HAC Express, the simulation test based on HiGale platform is even more powerful.

Convenient operation, friendly user interaction, unified model management, and good hardware performance enable the HAC Express platform to meet users' demands for high-speed and high-precision simulation modeling.

Product introduction

The Runke general HAC Express tool can increase the simulation step size of the model to the nanosecond level, which is 100 to 1000 times that of the traditional x86 simulator. At the same time, each running platform is equipped with a large number of distributed analog and digital interfaces to meet the needs of the model for IO resource interfaces. In addition, there is a high-speed data transmission interactive channel between multiple models to realize multi-model real-time simulation with low delay. At the same time, it supports seamless integration with HiGale simulation platform to realize joint simulation with other models.

Product advantage

Modeling and interface configuration are more convenient, one-click compilation and download

The software provides model and hardware equipment management functions to help users standardize their R & D process and manage their timeliness.

With flexible hardware modules and rich IO resources, it can meet the needs of multi-scene customization from single component to integrated power electronic system.

Application case

Some unit integrated electronic FPGA high-speed simulation test platform

In order to ensure the reliability of the traction control unit (TCU), the key component of the train traction system, reduce the risk of outflow of problematic parts, and reduce the research and development cycle, a HIL simulation test platform for traction circuit of TCU components was built. But the traction circuit is assembled by main transformer, converter and traction motor. The converter consists of a four-quadrant rectifier (4QC), a DC intermediate circuit and a drive inverter. In the process of HIL simulation, the model of the whole traction circuit is huge and needs many IO resource interfaces. Usually, the solution is to split the model into each board according to the size of the model supported by a board or the number of IO resources. In this process, the data exchange time between the decoupled models is long, and the robustness of the system after the model split is very high. Once the decoupling is not good, it will lead to the collapse of the whole model in the running process.

Taking transformers, precharging, intermediate DC circuits and inverters as examples, each circuit needs to include 150 digital input interfaces, 30 analog output interfaces and 10 analog input interfaces. Usually, this part of the circuit will be disassembled into 2 or 4 FPGA simulation boards to run, which is difficult to split. The structure block diagram of the parallel converter is shown below.

Now, using HAC Express tool, we can run complete transformer, precharge, intermediate DC circuit and inverter model without dismantling the model. at the same time, many IO connection requirements can be realized, which reduces the difficulty of design and improves the reliability of the model. For example, for the simulation part of a single motor TCU traction system, the topology of the HAC Express tool equipment is as follows:
