If we browse to the library location in Vivado i.e. <Vivado_Install_Location>\data\verilog\src, you would see that there is no folder by the name of simprims which is otherwise present in ISE at location <ISE_Install_Location>\ISE_DS\ISE\verilog\src.
Why Don't I See the SIMPRIM Library as in ISE?
Vivado has further unified the simulation libraries and now we don't have two simulation files for a single primitive. In ISE we used to have files as:
Unisims folder - AND2.v - For Behvaioral/Netlist simulation
Simprims folder - X_AND2.v - For Timing simulation only
These two files are now merged and the resultant file is present in the unisims folder present in location <Vivado_Install_Location>\data\verilog\src\unisims
This is done by using a macro- XIL_TIMING.
Example for AND2 in Vivado:
