In the 2019.1 release, compile_simlib fails to compile some IPs for VCS and Cadence Simulators (IES and Xcelium).
The "hdmi_gt_controller_v1_0_0" IP fails to compile with the following error message:
IES and Xcelium:
The "sync_ip" IP fails to compile with the following error message:
To work around this issue for the "hdmi_gt_controller_v1_0_0" IP, add "`timescale 1ns/1ps" to the following file and re-generate the compiled libraries.
You can ignore these failures if your design does not include the IPs in question.
If you are using these IPs in the design, other simulators can be used for simulation as a work-around.
The issue will be fixed in the 2019.2 release.
