使用create_clock、create_generated_clock等命令来定义时钟信号,并指定其频率、相位等属性。 确保时钟信号连接到元件: 检查设计,确保所有时钟信号都正确连接到了需要它们的元件上。 如果时钟信号是通过MUX选择的,确保MUX的输入和输出都正确连接。 调整综合策略: 降低综合策略的优化级别,以避免过度优化。 使用set_opti...

For simulation purposes, it is not necessary to create a clock for the Watch testbench, since the design already has the OSC4 component generating a 15Hz signal. However, one problem with this is that the OSC4 component also has a 8MHz pin, and therefore the OSC4 simu- lation model ...
