get_name in uvm





Classes deriving from uvmobject must implement the pure virtual methods such as create and gettypename.of this object. The default implementation is the same as getname, as uvmobjects do not inherently possess hierarchy. Unqualified names in an unrestricted in-lined constraint block are then resolved by searching first in the scope of the randomize() with object class followed by aThe uvmconfigdb::set() and get() calls get eliminated and also the entry from uvmconfigdb for each virtual interface handle got eliminated. Did not use UVM-1.0EA. 2011 Adopted UVM 1.0-p1. Converted OVM testbench to UVM. Copyright 2011 Boeing.

There is nothing to discuss about uvmtest class except uvmcomponent. UVM supports 2 types uvmobject and uvm component. The operation of the both refmods are quite simple: they just get the transactions (strings with messages) coming from theuvmtlmfifo (T) fromrefmod uvmtlmfifo(T) fromrefmodlow T tr1, tr2 int match, mismatch function new(string name, uvmcomponent parent) uvmconfigdb::set and uvmconfigdb::get methods are used to store and retrive the information from database respectively.bit uvmconfigdb(type Tint)::get(uvmcomponent cntxt, string instname, string field name, ref T value) The number of methods for uvmconfigdb are limited mainly 4 such as get,set,exists and waitmodified while the methods for uvmresourcedb are more like getbytype,getbyname Digging deeper into the UVM source code reveals that getconfigint is a function that looks like this (as defined in uvmcomponent.svh): typedef uvmconfigdb(uvmbitstreamt) uvmconfigint function bit uvmcomponent::getconfigint (string fieldname, inout uvmbitstreamt value) if(sequencer null) begin uvmreportfatal("SEQ","neither the items sequencer nor dedicated sequencer has been. supplied to start item in ", getfullname(),UVMNONE) return The following example demonstrates the UVM simulation phases and component hierarchy information methods. It includes a composition of street, city, and state, and illustrates the getchild(), getparent(), and getfullname() capabilities.

sformatf ("Medium level message"), UVMMEDIUM) uvmreportinfo (get typename (), sformatf ("High level message"), UVMHIGH) uvmreportinfoIf you have configured it to UVMLOW, then only UVMLOW and UVMNONE lines will be dumped out. Default configuration is UVMMEDIUM. uvmwarning(gettypename(), "isactive field in configdb conflicts with config object").sformatf("regs[0d]: s", j, regs[j].getname()), UVMHIGH) endfunction. A register sequence that reads or write registers in a register model should extend uvmsequence and should have a variable The UVM class uvm cmdline processor provides a mechanism to capture the command line argument and pass to verification components the testcase name. color)) 16 uvm fatal(GET NOTSUCC. The Universal Verification Methodology (UVM) is a standardized methodology for verifying integrated circuit designs. UVM is derived mainly from the OVM (Open Verification Methodology) which was, to a large part, based on the eRM (e Reuse Methodology) The gettypename() macro returns the class type name, which is often added in abbreviated form by the user in the uvminfo messages, but all of131 - Section 6.

2.1: Replace the display command with. uvminfo("FACTORY", sformatf("type of object is: s", gettypename()), UVMDEBUG). uvmresource(T) rsrc rsrc uvmresource(T)::getbyname(scope, name, rpterr) val While these calls are not particularluy complicated, coding all those low-level calls can be tedious and error prone. use "uvmroot::get()" when referencing upwards in Heirarchy use uvmtesttop or "" as inst name.uvmconfigdb ( type T int )::get( uvmcomponent cntxt , string inst name , string fieldname , ref T value ) fieldname must be same during get set, because while getting from uvmdatabse it will find for field name. value is the thing or resource which is actually going to be put into the database. With no strict guidelines from UVM documentation on what to use as ID, teams tend to misuse this quite a bit. Seasoned engineers tend to use built- in uvmobject::getname() as ID as that tends to make the log file comprehendible and correlates quickly to the objects in UVM. Get the address maps instantiated in this block. virtual function uvmmem getmembyname ( string name). Finds a memory with the specified simple name. INFO.

Setting up a variable in the environment hierarchy lets see who wins :) Winning Criterion: case 1: set is called in build phase uvmtesttop will get highest precedence (default 1000), next level below in environment hierarchy will have (highest via export (red circle).

Figure 9 - Proposed UVM Change - new definition for uvmobjectutils(T). If it is determined that there are no backward compatibility issues, I request that the UVM Standards Committee implement this change. uvmroot uvmtop uvmroot::get() uvmconfigdb(T)::set(uvmtop, inst name, fieldname, Notice that the global UVM root static class is used here for the context. Its primary role is to define a set of methods for such common operations as create, copy, compare, print, and record.
