uvm_analysis_imp_decl macro

NEED for uvm_analysis_imp_decl macro

Sometimes in the same component we need to have two analysis "Imp" export. For example, In Scoreboard we want to compare the data coming from tx_monitor of Agent1 with the data coming from rx_monitor of Agent2. 

So to get the transactions from two different component we have to have two analysis "Imp" export in the same component. One which will be connected with tx_monitor and other which will be connected with rx_monitor. Here, for two analysis "Imp" export we can not define the same write() method for both. So UVM provides the solution by defining the macro `uvm_analysis_imp_decl macro. This macro allows to declare a specialized "imp"-style analysis export, by which its function write can be renamed as write_SUFFIX. 

Code:

`uvm_analysis_imp_decl(_TX) `uvm_analysis_imp_decl(_RX) class my_scoreboard extends uvm_scoreaboard; uvm_analysis_imp_TX #(alu_txn, delay_analyzer) tx_export; uvm_analysis_imp_RX #(alu_txn, delay_analyzer) rx_export; ... function void write_TX(T t); ... endfunction function void write_RX(T t); ... endfunction endclass
