Question

我想创建一个只能在build_phase（）期间调用的函数。（在其他阶段进行调用会产生致命错误。）

如何找出我所在的uvm_phase？

Answer 1

您在中的阶段由* _phase方法的阶段参数表示。没有单个状态表示当前状态，因为UVM具有可以同时活动的许多可能的相域。因此，在调用它时，您必须将阶段传递给函数：

function void my_function(uvm_phase phase); if (!phase.is(uvm_build_phase::get()) `uvm_fatal(...); endfunction

或者，如果此函数是从uvm_component派生的类的方法，则可以覆盖phase_started方法

class my_component extends uvm_component; protected uvm_phase m_current_phase function void phase_started(uvm_phase phase); super.phase_started(phase); m_current_phase = phase; endfunction : phase_started function void my_function(..); if (!m_current_phase.is(uvm_build_phase::get()) `uvm_fatal(...); endfunction

Answer 2

class test extends uvm_test; function void print_cur_phase(); m_current_phase.print(); endfunction // print_cur_phase function void build_phase(uvm_phase phase); print_cur_phase(); endfunction // build_phase task run_phase(uvm_phase phase); print_cur_phase(); endtask // ... endclass中有一个名为# Gems gem 'ckeditor', github: 'galetahub/ckeditor' gem 'mini_magick' gem 'carrierwave' gem 'cloudinary' # Uploader class CkeditorPictureUploader < CarrierWave::Uploader::Base include Ckeditor::Backend::CarrierWave include Cloudinary::CarrierWave include CarrierWave::MiniMagick [:extract_content_type, :set_size, :read_dimensions].each do |method| define_method :"#{method}_with_cloudinary" do send(:"#{method}_without_cloudinary") if self.file.is_a?(CarrierWave::SanitizedFile) {} end alias_method_chain method, :cloudinary end # ckeditor/config.js // The location of an external file browser, that should be launched when "Browse Server" button is pressed. config.filebrowserBrowseUrl = "/ckeditor/attachment_files"; // The location of an external file browser, that should be launched when "Browse Server" button is pressed in the Flash dialog. config.filebrowserFlashBrowseUrl = "/ckeditor/attachment_files"; // The location of a script that handles file uploads in the Flash dialog. config.filebrowserFlashUploadUrl = "/ckeditor/attachment_files"; // The location of an external file browser, that should be launched when "Browse Server" button is pressed in the Link tab of Image dialog. config.filebrowserImageBrowseLinkUrl = "/ckeditor/pictures"; // The location of an external file browser, that should be launched when "Browse Server" button is pressed in the Image dialog. config.filebrowserImageBrowseUrl = "/ckeditor/pictures"; // The location of a script that handles file uploads in the Image dialog. config.filebrowserImageUploadUrl = "/ckeditor/pictures"; // The location of a script that handles file uploads. config.filebrowserUploadUrl = "/ckeditor/attachment_files"; config.allowedContent = true; # In the forms: <%= f.cktext_area :body, class: 'form-control ckeditor' %>的字段，其中包含最近执行的阶段。该字段在技术上不是标准API的一部分，但评论显示开发人员正在考虑为其添加一个访问器：

def public_id
  return model.user.id
end

最便携的方法是定义你自己的变量，就像戴夫在答案中所表达的那样。

Answer 3

uvm_component :: new检查build_phase完成后是否创建了组件（删除了错误消息）：

begin
  uvm_phase bld;
  uvm_domain common;
  common = uvm_domain::get_common_domain();
  bld = common.find(uvm_build_phase::get());
  if (bld == null)
    uvm_report_fatal(...);
  if (bld.get_state() == UVM_PHASE_DONE) begin
    uvm_report_fatal(...);
  end
end

这使用公共域和uvm_build_phase的单例getter，因此您不需要在本地手动跟踪任何阶段启动/状态，并且可以在调用函数时检查这些。

如何检查我是否在UVM的build_phase中？
