Spectre is different from SPICE in that it allows you to specify the parameters for several waveshapes at the same time, but then it also requires you to specify which waveshape you want. To do so, you use the "type" parameter. Possible values are "type=dc", "type=sine", "type=pulse", "type=pwl", etc.
This feature is convenient because it allows you to quickly switch between input waveshapes by changing the value of a single parameter, which can manually between runs or using the alter statement within a single run (oh yes, Spectre also allow you to have multiple transient analyses).
