`tvip_axi_master_item` and `tvip_axi_slave_item` have different random constraints for `tvip_axi_item::data` variable. * https://github.com/taichi-ishitani/tvip-axi/blob/21a3bfc5f4137fa032b655b43f4ea83ae6f3b368/src/tvip_axi_item.svh#L266 * https://github.com/taichi-ishitani/tvip-axi/blob/21a3bfc5f4137fa032b655b43f4ea83ae6f3b368/src/tvip_axi_item.svh#L346 This pattern would cause SEGV error below. ``` ERROR: [XSIM 43-3316] Signal SIGSEGV received.
