mentor and Cadence is as ugly as it is. Especially that line. It's really not easy to draw a line that doesn't bend. Later, because of the relationship between a project and learn the mentor company software, give me the most impressive is the mouse gesture recognition, other because of the basis of CR-5000, learning is still very fast. Later I used cadence, orcad, some work needs, some self-taught, and no
. It is necessary to set the parameters of the 3D body.Let's talk about the rotation of 3D models in AD. See XYZ three directions on the chart belowDouble-click the Model pop-up 3D Body dialog box, in the generic STEP model of the rotation x/y/z, you can set the direction and angle of the model rotation respectively.Rotation x indicates rotation with X axisRotation y indicates rotation with y as AxisRotation Z indicates rotation with Z axisstandoff Height You can set the model to move up or down
After the preliminary software plan and the overall plan ("What is it ?"), Then we began to analyze and design requirements. This was an essential stage before the coding stage. This stage had a thorough analysis and design, so that coding could be carried out in an orderly manner, Requirement analysis: the key is to fully analyze the customer's requirements,

A "scene tree"; an extremely simple and lightweight practice that enables develo
clear service concepts are not covered in the discussion ), all functional-oriented designs are vulgar designs. Under the influence of such functional-oriented service ideas, the division of service granularity will never be clear, and there is no abstraction based on the nature of the business, it is a specific and easy-to-change function. In this case, the discussion about service granularity is meaningless. In fact, it is only necessary to compile
problem. Later asked colleagues they said they have done so ... 囧Method Two:In the design of a new version of the software, on the one hand, the standardization of the industry, regional industry standards have emerged, on the other hand, the new system focused on the overall solution, not for the old project transformation, this problem is not taken seriously. But I have a hunch that business-based consid
A software architecture is a structured element with a certain form, that is, a set of components, including processing components, data components, and connection components. Architecture issues include the overall organization and global control, communication protocols, synchronization, and data access, assigning specific functions to design elements, and the organization, scale, and performance of
Software timers in the protocol stack and many other scenarios have a wide range of applications, sometimes there will be a large number of timers at the same time in the work state, their time-out is different, to effectively ensure that each timer can be more accurate time-out and execute to its callback function is not an easy task. This paper analyzes the timer scheme of embedded real-time operating sys

. The general framework of Instant Messaging deployment is also mentioned. Now, let's look at the technical difficulties. Some functional points that will not spread are not difficult. Just do it. Therefore, in the initial stage of software design, we should consider the difficulties that are easy to expand globally, just like cancer is in the blood. Don't fix i
servers are used, when one server goes down, only part of the data in the system is unavailable, not all. Therefore, database splitting can not only use multiple servers to share the load pressure on the database, but also improve the overall availability of the system. There are two ways to split data::Vertical Split and horizontal split.1.1 Vertical Split Vertical splitting refers to splitting the data tables accessed by each module into different databases according to the system function mo
