UVM

Hi All,
I want to pass a two dimensional array using uvm_config_db set and get method.
I tried a using typedef, but failed.
Any help is appreciated.

Thanks,

Could you please Elaborate a Little bit more. You can pass any data type to the config_db, including class-based data types.

Please show an example and explain how it failing.

BTW, we strongly recommend limiting the number of configuration variables and grouping them into class configuration objects.

Hi chr_sue/Dave,
I got the solution. I am not sure it is corrector not.
bit [0:288] tx_size3_bit_lane_slot_mem [0:39];
//Config_db set
foreach(tx_size0_bit_lane_slot_mem[i])
uvm_config_db#(bit [0:288])::set(null, “*”, $sformatf(“tx_size3_bit_lane_slot_mem[%0d]”,i), tx_size0_bit_lane_slot_mem[i]);
//Config_db get
foreach(tx_size3_bit_lane_slot_mem[i])
uvm_config_db#(bit [0:288])::get(null, this.get_full_name(), $sformatf(“tx_size3_bit_lane_slot_mem[%0d]”,i), tx_size3_bit_lane_slot_mem[i]);

Thanks,

This is a very inefficient way to use the uvm_config_db() and can potentially lead to some significant performance impact. You should really follow Dave’s advice and use a class configuration object.

In reply to cgales:

The question is how many additional values you are passing to the config_db.
If you have only the virtual Interfaces, maybe a Register model and some values it is fine.
If you have more values you want to pass to the config_db and you might randimize These values it is highly recommended you are using a configuration object (configuration class). If you are using such a class don’t Register this with the registry. This gives you the freedom to write your own constructor with individual Arguments.
