Can't generate TB for Cyclone10GX_PCIeGen2x4_DMA_18_0_project

Which version of Quartus are you using and which PCIe DMA IP have you used? Is this Project only using this IP or are there any other IPs in use?

I downloaded

AN 829: PCI Express Avalon -MM DMA Reference Design for ​Quartus Prime 18.0.0 Pro from

https://fpgacloud.intel.com/devstore/platform/?acds_version=18.0&family=cyclone-10-gx.

This is the only design in Project with nothing else added.

Yes and I am using ​Quartus Prime 18.0.0 Pro.
