今天下午用Cadence的ams仿真ADPLL,模拟和数字模块都已经弄好了,elaborate也完成了,然后就出现“AMSD has detected that the LD_ASSUME_KERNEL environment variable is set. The tool will not run because this may lead to unexpected behavior during simulation. You must unset the LD_ASSUME_KERNEL environment variable.”的error,无法仿真下去,有人知道这是出了什么问题吗?应该怎么解决?
