ecpratik Posted November 21, 2012 Report Share Posted November 21, 2012 Hello , I have one requirement in which I want to convert my tesbench (which instantiate multiple OVCs) from OVM to UVM Before I convert whole OVC into UVC , is it possible to change only top testbench from OVM to UVM without changing sub level components (and OVCs) which are used in that test bench into UVM ? Or we must have to change whole test bench and OVCs into UVM compliant ? Thanks. Quote Link to comment Share on other sites More sharing options...
jadec Posted November 30, 2012 Report Share Posted November 30, 2012 You have to change the whole thing. There's no way to interoperate OVM and UVM. On the other hand, the conversion is generally an automated process, you have more flexibility in incrementally removing the deprecated OVM features.

uwes Posted December 3, 2012 Report Share Posted December 3, 2012 basically you got the following: - running OVM/UVM in co-existence mode (no no dependencies, no direct interaction): this should work out of the box (but thats not what you want) - running OVM/UVM jointly: requires several things incl. phase synchronization - NOT really recommended - convert all OVM to UVM using the script - typically the fastest route - use a facade around uvm exposing it as ovm. kind of typedef uvm_void ovm_void; typedef uvm_root ovm_root; typedef uvm_factory ovm_factory; typedef uvm_object ovm_object; typedef uvm_transaction ovm_transaction; typedef uvm_component ovm_component; ... this CAN work but might get problematic if you are using or utilizing OVM specials. so yes there are some way to do that but as jade says typically its best and fastest to migrate. in addition to the other ways this path is known and quite some documentation exists. /uwe Quote Link to comment Share on other sites More sharing options...
ecpratik Posted December 7, 2012 Author Report Share Posted December 7, 2012 Thanks jadec and uwes for your replies. After lot of try and error , I found easiest way which was to convert OVM test bench to UVM test bench rather to keep test bench partial of OVM and UVM.
