仿真问题

Trouble Writing Register PC: (Error -1176 @ 0x8580) Unable to access device memory. Verify that the memory address is in valid memory. If error persists, confirm configuration, power-cycle board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 5.0.681.0) 不知道是怎么回事，希望可以得到帮助

noaming：

降低JTAG口TCLK频率试试看。另外，仿真器型号配置，以及仿真器驱动等检查一下，看是否都正确。
