Many simulators except for Cadence Spectre had enhanced controlled sources which were familiar in HSPICE or PSPICE.
Also many model files provided from foundary are written in HSPICE netlist.
So "bsource" was introduced into Cadence Spectre for porting HSPICE model file which includes enhanced controlled sources.
So Cadence doesn't provide spectre view of bsource.
But you can use bsource in netlist.
See the result of "spectre -h bsource".
Actually any bsources are replaced to Verilog-A internally in Cadence Spectre.

E1 a b vol=v(n1,n2)*k max=cc min=0
Verilog-A is so strong while if the expression quote many voltage or current it need many input/output port.
