模擬DDR4 SDRAM MIG v2.2時, 出現FATAL_ERROR: Vivado Simulator kernel has discovered an exceptional condition from which it cannot recover.

各位好,我的vivado版本為2018.2和2018.3,平台型號為VCU1525。

目前模擬MIG時發生了問題,如果只是單純建一個DDR4 SDRAM MIG v2.2的IP並生成example design來模擬,看起來一切正常,但是把MIG連接AXI INNERCONNECT和 PCIe DMA(DMA/Bridge Subsystem for PCI Express v4.1) ,只是拿example design簡單的連接起來,test bench也是拿example design修改串聯而已,模擬時就會發生如下錯誤,試過vivado 2018.2和2018.3情況完全相同:

FATAL_ERROR: Vivado Simulator kernel has discovered an exceptional condition from which it cannot recover. Process will terminate. For technical support on this issue, please open a WebCase with this project attached at http://www.xilinx.com/support.

File: D:/5_Fiber_DDR_PCIe/PCIe_DDR4_0312_board/xdma_0_ex/xdma_0_ex.srcs/sim_1/imports/imports/ddr4_model.sv

在此附上design top及sim top,網路上實在找不到答案,需要各位的幫忙,非常感謝!

Fatal Error多数为工具问题,需要进一步调试看看是否能有方法绕过。看上去是跟ddr4_model.sv的某些进程有关。

如果有第三方仿真器,也可以一并跑一下,看是否能跑过或者有其他错误提示。
