I have the following warning which I do not understand:
Warning from spectre at time = 536.062 us during transient analysis `tran'.
WARNING (AHDLLINT-8004): "tb_disciplines.vams" 537: hvbms_tb.dut.vana_pad__R2E_supply__wreal_supply._cds_internal_R2E_supply_: Non-piecewise constant argument is detected in the transition filter. The transition filter can only be applied to piecewise constant signals. The argument must be redefined to ensure that the transition filter applies only to a piecewise constant signals.
What is a piecewise constant? Can anyone help?
