Pin grid array (PGA) ApplicationThis package is equipped with advanced IC chips, such as ASIC, used mainly for the mpu of a computer and communications equipment.
引脚网格阵列(PGA)用途主要供给高阶ic使用如在ASIC等高功能芯片，主要使用于计算机的MPU或通信设备等里面。
If a cell width is not a multiple of the pin grid, even though its pins are on the grid, the cell will cause the cells adjacent to it to be misaligned with respect to the grid.
如果一个单元宽度不是PITCH的倍数，即使它在引脚的网格点上，也会导致邻近的单元在网格上不对齐。
Every pin should cover at least one grid intersection, because the software connects most efficiently to pins at grid intersections.
每个引脚应该覆盖至少一个网格交叉点，由于软件连接最有效的是引脚在网格交叉点上。
The pin rectangle encloses the grid intersection point on all four sides by half the minimum metal width of that pin shape layer.
引脚围绕网格交叉点成矩形，在引脚图层通过最小金属宽度的一半指向所有四边。
The router only routes to the center of off-grid pin port rectangles, if this is legal.
如果这是合规矩的，布线器就布线到非网格交叉点的中心。
Pin a has several off-grid shapes and one on-grid shape.
引脚a有多个非网格形状和一个网格图形。
Pin a has several off-grid shapes and one on-grid shape.
引脚a有多个非网格形状和一个网格图形。
