模拟电子  射频集成电路设计John Rogers(Radio Freq

Radio Frequency Integrated Circuit Design I enjoyed reading this book for a number of reasons. One reason is that itaddresses high-speed analog design in the context of microwave issues. This isan advanced-level book, which should follow courses in basic circuits andtransmission lines. Most analog i ...

Mentor Design Safe Verilog State Machine（Synplicity）

&nbsp; One of the strengths of Synplify is the Finite State Machine compiler. This is a powerfulfeature that not only has the ability to automatically detect state machines in the sourcecode, and implement them with either sequential, gray, or one-hot encoding. But alsoperform a reachability ana ...

Mentor Creating Safe State Machines(Mentor)

&nbsp; Finite state machines are widely used in digital circuit designs. Generally, when designing a state machine using an HDL, the synthesis tools will optimize away all states that cannot be reached and generate a highly optimized circuit. Sometimes, however, the optimization is not acceptabl ...

PCB相关  PCB设计问题集锦

PCB设计问题集锦问：PCB图中各种字符往往容易叠加在一起，或者相距很近，当板子布得很密时，情况更加严重。当我用Verify Design进行检查时，会产生错误，但这种错误可以忽略。往往这种错误很多，有几百个，将其他更重要的错误淹没了，如何使Verify Design会略掉这种错误，或者在众多的错误中快速找到重要的错误。　　　答 ...
