Global Clocks

In the QuickSD device, there are nine global clock networks: one is dedicated and eight are

programmable . Global clocks can drive logic cell, I/O, ECU blocks and RAM registers in the

device. Five global clocks will have access to a Quad Net (local clock network) connection

with a programmable connection to the register inputs. Figure 49 gives the global clock

methodology

Figure 49: Global Clock

Quad-Net Network

There are five Quad-Net local clock networks in each quadrant for a total of 20 in a device.

Each Quad-Net is local to a quadrant. Quad-Net is multiplexed with the clock buffer before

driving the column clock buffers.
