(1) user在构建register model或者集成register model的过程中,可能会调用uvm_reg::build_coverage(), uvm_mem::build_coverage(), uvm_reg_block::build_coverage();而在build_coverage()函数内,会调用uvm_resource_db::read_by_name()函数,该函数又会调用get_by_name()函数,接着调用uvm_resource.svh中的...

This paper will go through the process of UVM Register model generation with its coverage model using Synopsys tools. We propose an efficient methodology to automatically update the register model with the changes of the hardware registers using a backdoor technique, especially the read-only ...
Model Based Testing:MBTmeans guiding generation using some (usually formal) model. For instance, if (in addition to the DUT itself) we get a formal “reference model” of its state machines, we can sometimes use model-checking-like techniques to achieve a “witness” which takes us to a d...
To implement the reference model direct programming interface (DPI) functionality of SystemVerilog is used. The reference model is the software implementation of the DUT written using the C-programming language. Design Under test: RCC Unit used in DTMF Receiver ...
Generate a UVM or SystemVerilog DPI Component Configure the Model for Code Generation In the Configuration Parameters dialog box, select Code Generation in the left pane. Under Target Selection, set System Target File to systemverilog_dpi_grt.tlc or to systemverilog_dpi_ert.tlc wh...
SystemVerilog functional coverage can help verification engineers that used to model the analog signals in digital environment in the following: Ensuring any “real” signal is covered under a certain amplitude This amplitude range could have tolerance due to any mismatch within the circuit. ...

Additional problems can be found with the existing coverage model once we start considering the system level. “What we have in place today works well at the IP level,” says Foster. “At the system level it totally falls apart. We need completely different ways to think about it.” ...
