Missing Features vs C++/Java and Reliable Workarounds
Beyond inheritance and operators, SystemVerilog lacks several C++/Java language features, so reusable DV design depends on explicit APIs, packages, wrappers, and status-code-based error flow.
Overview
Beyond inheritance and operators, SystemVerilog lacks several C++/Java language features, so reusable DV design depends on explicit APIs, packages, wrappers, and status-code-based error flow.
Key gaps compared with C++/Java include: no template functions or broad generic algorithms beyond parameterized classes, no friend access control, no C++-style const-correctness, packages instead of hierarchical namespace systems, no class method overloading by signature, and no exception/try-catch mechanism.

SystemVerilog versus C++ OOP matrix
SV VS C++ FEATURE MATRIX
+------------------------+-------------------+------------------------+
| capability | SystemVerilog | C++ |
+------------------------+-------------------+------------------------+
| multiple inheritance | no | yes |
| interfaces as classes | interface class | abstract class idiom |
| templates | parameterized cls | templates |
| memory control | GC-like handles | manual/RAII/smart ptr |
| reflection/factory use | common in UVM | framework dependent |
