The paper proposes a fast algorithm for solving the FPGA routing problem on a mixed routing graph. The main idea behind it is to introduce some algorithmic enhancements to classic Pathfinder based on replacing the total routing tree rip-up with partial rip-up. A new formula for calculating routing element costs that considers the rip-up results and reduces congestion rates in further router iterations is also presented. The operation of the algorithm was tested on the popular digital benchmarks ISCAS'85, ISCAS'89, LGSynth'89, IWLS'2005, and a number of projects from *** on an FPGA from the 5510TC028 system-on-a-chip. The stages of the layout synthesis flow preceding routing stage were carried out using the X-CAD computer-aided design system for FPGA design. The experimental results demonstrate an average routing runtime reduction of 2.8 times compared to the default X-CAD flow. No significant impact on the timing characteristics estimated with the open-source tool OpenSTA was observed. © 2024 ieee.

Space systems are continuously under cyber attack. Minimum cybersecurity design requirements are necessary to preserve our access to space. This paper proposes a scalable, extensible method for developing minimum cyber design principles and subsequent requirements for a space system based on any given mission priority. To test our methodology, we selected the fundamental mission priority of preserving access to space by preventing the permanent loss of control of a satellite. We then generate the minimum number of secure-by-design principles that can collectively prevent the permanent loss of control of a satellite and translate these into example minimum requirement 'shall' statements. Our proposed minimum requirements methodology and example can serve as a starting point for policymakers aiming to establish security requirements for the sector. Further, our methodology for establishing minimum requirements will be engaged for prioritizing the efforts of the emergent ieee International Technical Standard for Space Cybersecurity (Working Group P3349).

To ensure that all types of control equipment in the industrial process control network are stable in the same clock reference for a long time, a highly reliable punctuality system is designed and implemented;Based on ieee1588v2 high-precision clock synchronization protocol, the system uses dual redundant clock synchronization technology to achieve high-precision clock synchronization with the master clock in the network. When it is unable to synchronize with the master clock, the system adjusts the local clock by calling the stored historical clock deviation value to improve the punctuality of the system;The test and verification platform is built to test the clock synchronization accuracy and punctuality accuracy. The test results show that the clock synchronization accuracy is within ± 500ns after the system runs stably, and the punctuality accuracy is within ± 20us/h after the system cannot be synchronized with the master clock to enter the punctuality state, which meets the design requirements. © 2024 ieee.

In the context of the digital transformation of the power industry, intelligent recommendation algorithms play an increasingly prominent role in improving human-computer interaction design. This research focuses on the exploration and practice of intelligent recommendation algorithm, especially random forest algorithm and ranking learning algorithm, in the power industry. In this paper, an intelligent recommendation model based on user behavior data is designed, which combines random forest algorithm and ranking learning method to optimize the user interface of power system. Through dynamic analysis of user behavior data, the model provides personalized recommendation content, and effectively improves the efficiency and satisfaction of user operation. In the system simulation part, a comprehensive evaluation model is constructed to simulate the performance of the algorithm under different operating scenarios. The simulation results show that the designed intelligent recommendation algorithm is superior to the traditional methods in terms of response speed and recommendation accuracy, especially in complex interactive scenarios. Through accurate data analysis, this paper verifies the applicability and robustness of the algorithm in different user groups. © 2024 ieee.

The issue of security in the process of digitalization of state-owned enterprises is becoming increasingly prominent. Due to the security issues inherent in security boundary protection devices themselves, traditional security solutions are finding it difficult to address the overall problem of network security. This paper proposes a network security access system design scheme based on zero trust. It uses cryptographic technology to perform user identity marking and authentication, preventing interception and reuse of user password information. Cryptographic technology ensures the confidentiality and integrity of critical data during transmission and storage, preventing data leakage or tampering. Finally, the effectiveness and feasibility of the proposed scheme are verified through its actual application in Beitou Cloud. © 2024 ieee.

With the rapid development of the DC distribution network, the method of limiting the rapid rise of current after a short-circuit fault on the DC side has become a research hotspot. This paper proposes a new DC fault current limiter (FCL) topology and its prototype design scheme. The topology converts DC into AC through the IGBT bridge during fault and uses the characteristics of low-frequency resistance and high frequency of reactor to limit current. Secondly, this paper optimizes the main equipment parameters of the proposed FCL prototype, selects the current limiting reactance, Hall sensor, drive plate and arrester, and uses AutoCAD to design the appearance and overall layout of the current limiting prototype. At the same time, the hardware and software of the control and protection system are designed. Based on the RS232 serial port, the software program communicates with the host computer to analyze the operating state of the current limiter under normal operation and fault period. Finally, the reliability and superiority of the FCL control system and current limiting characteristics proposed in this paper are verified by comparing the experiment with the RT-LAB semi-physical simulation data.

Formal Synthesis of Adaptive Droplet Routing for MEDA Biochips

A digital microfluidic biochip (DMFB) enables the miniaturization of immunoassays, point-of-care clinical diagnostics, and DNA sequencing. A recent generation of DMFBs uses a microelectrode-dot-array (MEDA) architecture, which provides fine-grained control of droplets and real-time droplet sensing using CMOS technology. However, microelectrodes in a MEDA biochip can degrade due to charge trapping when they are repeatedly charged and discharged during bioassay execution;such degradation leads to the failure of microelectrodes and erroneous bioassay outcomes. To address this problem, we first introduce a new microelectrode-cell design such that we can obtain the health status of all the microelectrodes in a MEDA biochip by employing the inherent sensing mechanism. Next, we present a stochastic game-based model for droplet manipulation, and a formal synthesis method for droplet routing that can dynamically change droplet transportation routes. This adaptation is based on the real-time health information obtained from microelectrodes. Comprehensive simulation results for four real-life bioassays show that our method increases the likelihood of successful bioassay completion with negligible impact on time-to-results.
