Virtex UltraScale+ HBM Controller - Simulation Issues with VCS, Questa Sim, or IES Simulators

描述

Version Found: HBM v1.0

Version Resolved: See (Xilinx Answer 69267)

Simulation errors will occur with the HBM IP when using VCS, Questa Sim, or IES simulators.  

Because these are the only supported simulators for the HBM IP the modifications below in the Solution section are required in all use cases.

Notes:

  • Vivado Simulator is not supported by the HBM IP
  • The solution steps assume that the simulation is being launched through Vivado.  If you are not launching the simulation through Vivado then these variables need to be manually added to the simulation test bench.

解决方案

This section describes the required modifications when using the supported Third party simulator tools with the HBM IP.

When using VCS:

  • Vivado 2018.2:
    • Add +notimingchecks to vcs.simulate.vcs.more_options under the Simulation tab in the Vivado Project Settings 
  • Vivado 2018.3 and Above:
    • Add +notimingcheck to vcs.simulate.vcs.more_options under the Simulation tab in the Vivado Project Settings

When using Questa Sim:

  • Vivado 2018.2 and Above:
    • Add +notimingchecks to questa.compile.vlog.more_options under the Compilation tab in the Vivado Project Settings
    • Add -onfinish final +notimingchecks to questa.simulate.vsim.more_options under the Simulation tab in the Vivado Project Settings

When using IES:

  • Vivado 2018.2 and Above:
    • Add -notimingchecks to ies.elaboration.ncelab.more_options under the Elaboration tab in the Vivado Project Settings

If issues persist when using Vivado 2018.3 and later versions of Vivado, see (Xilinx Answer 71795)
