OEM Modelsim: Modelsim for iCECube2 does not allow me to simulate my design on pre-synthesis; Error involve instantiation of modules as shown below:Error: (vsim-3033) Instantiation of 'SB_HFOSC' failed. The design unit was not found.Error: (vsim-3033) Instantiation of 'SB_IO_OD' failed. The design unit was not found.

Description:
Users encounter a design unit failure when utilizing Hard blocks from their iCECube2 Design.

Solution:
The simulation error is encountered if the design is utilizing Hardened Ips/Primitives,the libraries sb_ice_syn.v and sb_ice_ipenc_modelsim.v must be added in your simulation project, the files are located in C:\lscc\iCEcube2.2020.12_v\verilog  or <iCECube2_Directory>\verilog
