就是全局复位，下面是关于GSR描述 X( ?# s" i/ h1 V% ~: O. c8 s
The GSR must be connected to all of the registers that you want the signal to go to in your design. This is different from FPGAs in which using the STARTUP block and connecting to the signal GSR globally sets/resets all flip-flops on the device.1 L" m$ E& Y! R) o$ J/ y- u& O: s; n6 ~ T
The GSR can be connected to either the Set or the Reset port of any registers in the device.$ V- }( H0 X. V) j0 j2 C1 W
简单的说，FPGA里所有的寄存器资源都要连接全局复位，这个复位信号可以从器件的任意可用管脚输入。 $ t2 z j5 L$ l# I$ P5 J/ J. ` d
