能否动态修改Origen参数集？含删除及新增键需求

Absolutely! You can dynamically modify Origen parameter sets to handle both of your requested operations. Let me walk you through how to do each one with clear, practical examples:

Deleting a Parameter Set #

Origen provides a straightforward method to remove an entire parameter set from your application's registry. Use the remove_parameter_set method, like so:

# First, define a sample parameter set
add_parameter_set :power_settings do
  param :core_voltage, 1.8
  param :io_voltage, 3.3
end

# Now delete the entire set
remove_parameter_set :power_settings

After running this, the :power_settings parameter set will no longer be available for use in your code.

Adding New Keys to an Existing Parameter Set #

There are two easy ways to add new parameters (keys) to an already-defined parameter set:

1. Re-open the Parameter Set Definition #

You can simply re-declare the parameter set with the new parameters you want to add. Origen will automatically merge these into the existing set instead of overwriting it:

# Original parameter set
add_parameter_set :communication_settings do
  param :baud_rate, 9600
end

# Re-open to add a new parameter
add_parameter_set :communication_settings do
  param :parity, :none
end

Now :communication_settings includes both :baud_rate and :parity.

2. Directly Modify the Parameter Set Object at Runtime #

If you need to add parameters dynamically during execution (for example, based on test results or user input), you can grab a reference to the parameter set and use the add_param method:

# Retrieve the existing parameter set
comm_params = Origen.app.parameter_sets[:communication_settings]

# Add a new parameter on the fly
comm_params.add_param :stop_bits, 1

This approach gives you flexibility to adjust parameter sets as your application runs.
