报错:
[USF-XSim-62] 'elaborate' step failed with error(s). Please check the Tcl console output or 'F:/vivado_project/timer/timer.sim/sim_1/behav/xsim/elaborate.log' file for more information.
[Vivado 12-4473] Detected error while running simulation. Please correct the issue and retry this operation.
[DRC BIVC-1] Bank IO standard Vcc: Conflicting Vcc voltages in bank 34. For example, the following two ports in this bank have conflicting VCCOs:
clk (LVCMOS18, requiring VCCO=1.800) and a_to_g[0] (LVCMOS33, requiring VCCO=3.300)
[Vivado_Tcl 4-23] Error(s) found during DRC. Placer not run.
原因:
clk及dp的VCCOS为默认的LVCMOS18,未进行更改。
解决:

本文详细解析了Vivado在运行模拟时遇到的错误,包括'elaborate'step失败、DRC检查错误以及放置操作未运行等问题。通过案例分析,指出问题在于信号clk及dp的VCCO标准冲突,提供了修改VCCO标准的解决方案。
