(OPT-1406)根据消息的严重性等级从轻到重可以分为信息(Info)、警告(Warning)、错误(Error)、严重错误(Severe Error)和致命错误(Fatal)可以使用一些命令对消息进行管理本文就将介绍这些命令。get_message_idsstring get_message_ids [-type severity] [pattern]get_message_ids命令可以根据模式串获得一条消息的ID 模式串中可包含通配符*与?并可以指定消息类型。下面展示了该命令的使用方式。dc_shell get_message_ids -type Error *1406 FPHSM-1406 OPT-1406set_message_infoset_message_info -id message_id -limit max_limit | -stop_on | -stop_offset_message_info命令用于对指定消息设置上限如果消息的严重性等级为Severe Error或Fatal则无法设置上限也无法被抑制出现次数超过上限后再次出现的消息将被抑制需要注意的是即使消息被抑制依旧会将其统计在出现次数中将上限设置为0表示无限制。该命令也可以将消息的严重性等级设置为Severe Error如果该消息是在脚本执行中出现的脚本将会立刻终止执行此时不管sh_continue_on_error变量的设置如何。下面展示了该命令的使用方式。dc_shell-topo set_message_info -id OPT-1406 -limit 2 dc_shell-topo set_wire_load_mode test Error: Command set_wire_load_mode is not supported in DC Topographical mode.

To see the Tcl call stack for the part of your script which generated the Severe error use the error_info command. (CMD-103) Error: Severe error encountered Use error_info for more info. (CMD-013)suppress_messagesuppress_message message_listsuppress_message命令可以无条件抑制严重性等级为Info或Warning的消息可以使用unsuppress_message命令取消无条件抑制同一条消息可以被多次抑制因此需要适应相应次数的unsuppress_message命令。下面展示了该命令的使用方式。dc_shell-topo get_cells test Warning: Cant find object test in design SNPS_CLOCK_GATE_HIGH_simple_register.
