  1. Dear all, I am new to payload extensions and I would appreciate a feedback on whether I am doing things right.. I need to declare a simple payload extension, including two additional fields: a reset value a 16 bit bit vector representing the value of a register In the header, I simply declare the clone/copy from functions, plus my additional fields: class reg_extension : public tlm::tlm_extension<reg_extension>{ public: reg_extension(); tlm::tlm_extension_base* clone() const ; void copy_from(tlm::tlm_extension_base const &); bool reset; sc_bv<16> value; }; And then I implemented the functions, by taking care of the additional reset and value fields: reg_extension::reg_extension(){ reset = false; value = sc_bv<16>(0); } tlm::tlm_extension_base * reg_extension::clone() const{ cout<<"Executing clone!"<<endl; reg_extension * ext = new reg_extension(); ext->reset = this->reset; ext->value = this->value; return ext; } void reg_extension::copy_from(tlm::tlm_extension_base const & ext){ reset = static_cast<reg_extension const &>(ext).reset; value = static_cast<reg_extension const &>(ext).value; } Is this enough for the extension to work? Best regards, S.
