WebNov 26, 2024 · I am working on a MAX10 10M50 device with Quartus Prime lite 2024.1.0 My design uses an external IO pin as a clock source. This pin is NOT a dedicatd clock pin. I instantiated a altclkctrl bock to route this pin to the global clock resource. The output of that block is connected to the input of a ... WebSep 21, 2024 · GCLKs are driven throughout the device and serve as low-skew clock sources for functional blocks such as adaptive logic modules (ALMs), digital signal processing (DSP) subcircuits, embedded memory, and PLLs. In addition to GCLKs, there are regional clock (RCLK) networks in the Intel FPGAs.

WebNov 2, 2010 · The ADC_CLOCK will pass through a CCB the a ouput pin to clock external ADC. Here is my questions: 1) Are these Clock Control Blocks absolutely needed? 2) With TimeQuest, only the 50MHZ can be constrained by create_clock, and all other clocks should be constrained by create_generated_clock. WebUse dedicated hardware to perform clock multiplexing when it is available, instead of using multiplexing logic. For example, you can use the Clock Switchover feature or the Clock Control Block available in certain Intel FPGA devices. These dedicated hardware blocks avoid glitches, ensure that you use global low-skew routing lines, and avoid any possible … literacy christmas activities
