本文主要介紹如何在Wado設計套件中進行時序約束,原文出自 xilinx中文社區。1 Timing Constraints in Vivado-UCF to xdcVivado軟件相比于sE的一大轉變就是約束文件,5E軟件支持的是UcF(User Constraints file,而 Vivado軟件轉換到了XDc(Xilinx Design Constraints)。XDC主要基于SDc(Synopsys Design Constraints)標準,另外集成了Xinx的一些約束標準可以說這一轉變是xinx向業界標準的靠攏。Altera從 TimeQuest開始就一直使用SDc標準,這一改變,相信對于很多工程師來說是好事,兩個平臺之間的轉換會更加容易些。首先看一下業界標準SDc的原文介紹:Synopsys widely-used design constraints format, known as sDc, describes the design intent"and surrounding constraints for synthesis, clocking, timing, power, test and environmental and operating conditions. sDc has been in use and evolving for more than 20 years, making it the most popular and proven format for describing design constraints. Essentially all synthesized designs use SDc and numerous EDa companies have translators that can read and process sDc

基于藥物治療在臨床治療中的重要性,分析目前服藥提醒裝置存在的不足,以STM32F103VET6單片機為控制核心,設計了一種多功能電子藥箱。該系統包括顯示模塊、語音模塊和數據存儲模塊。顯示模塊通過觸摸屏電路和LED指示燈電路,與語音模塊相配合,實現了服藥提醒及指導的功能;數據存儲模塊通過EEPROM存儲電路,能夠實現掉電時服藥信息不丟失的功能。并且為了實現電子藥箱的智能化控制,開發了手機APP,兩者之間可通過WIFI進行數據通信。經測試,該藥箱能夠有效地幫助慢性病患者按時、定量、正確服用藥物,適合在家庭中推廣使用,具有較高的應用價值和實踐意義。Based on the importance of drug therapy in clinical treatment, this paper analyzes the shortcomings of current drug reminder devices, and designs a multi-function electronic medicine box with STM32 F103 VET6 microcontroller as the control core. The system includes a display module, a voice module, and a data storage module. The display module cooperates with the voice module through the touch screen circuit and the LED indicator circuit to realize the function of reminding and guiding the medicine;the data storage module can realize the function of not losing the medication information when the power is off through the EEPROM storage circuit.After testing, the medicine box can effectively help chronic diseases patients to take drugs on time, in a quantitative and correct manner,and is suitable for popularization in the family, and has high application value and practical significance.
