使用 SQL 合计函数 你可以确定数据组的各种统计。你可以把这些函数用于查询和合计表达式，条件是在具备 SQL特性的 QueryDef对象中或在创建基于SQL查询的 Recordset对象时-You use the SQL aggregate functions to determine various statistical data sets. You can put these functions together for query and expression, on the condition that the availability of SQL characteristics QueryDef object or create a SQL query based on the Recordset object

使用函数实现简单的八位处理器 软件开发环境：ISE 7.1i 仿真环境：ISE Simulator 1. 这个实例实现通过ISE Simulator工具实现一个可以进行两个八位操作数四种操作的简单处理器； 2. 工程在project文件夹中，双击mpc.ise文件打开工程； 3. 源文件在rtl文件夹中，mpc.v为设计文件，mpc_tb.tbw是仿真波形文件； 4. 打开工程后，在工程浏览器中选择mpc_tb.tbw，在Process View中双击“Simulation Behavioral Model”选项，进行行为仿真，即可得到仿真结果。-The use of a simple function to achieve the eight-processor software development environment: ISE 7.1i simulation environment: ISE Simulator 1. This example through the ISE Simulator tool to achieve the realization of a two operand four of eight simple processor operation 2. works in the project folder, double-click to open the project file mpc.ise 3. rtl source file in the folder, mpc.v documents for the design, mpc_tb.tbw is the simulation waveform files 4. to open a project, a browser in the works Select device mpc_tb.tbw, double-click in the Process View in the " Simulation Behavioral Model" option, to carry out acts of simulation, simulation results can be obtained.
