e Reuse Methodology
 |
The e Reuse Methodology (eRM) was the first reuse methodology to emerge in the Hardware Verification Language space and was used in conjunction with the e Hardware Verification Language. It was invented in 2001 by Verisity Design and was released in 2002. The methodology was composed of methodology guidelines for such topics as:
- File naming conventions
- Functional partitioning of the testbench
- Code packaging Guidelines
- Sequence and message class libraries
The e Reuse Methodology was widely accepted by verification engineers and, to this day, is the most widely used and successful reuse methodology with thousands of successful projects. [citation needed]
eRM formed the basis of the URM (Universal Reuse Methodology) developed by Cadence Design Systems for the SystemVerilog Language. URM, together with contribution from Mentor Graphics' AVM, later went on to become the OVM (Open Verification Methodology) and, finally the UVM (Universal Verification Methodology) today.[citation needed]
