The invention relates to a method comprising the following steps: HDL instruction sequences which are to be at the origin of memory elements during the synthesis of the system are automatically localized in the original HDL description files; and so-called SCAN HDL instructions are inserted into at least some of the HDL description files in an automatic sequential manner and without relational or functional analysis of the identified memory elements, ensuring that at least one so-called SCAN channel is obtained during the synthesis of the system, linking the memory elements.

Method for creating HDL description files of digital systems, and systems obtained

The present invention relates to the testing of functional or IP cores forming part of a system on chip, SoC. The invention is implemented using a testing means and a communication means to test at least one functional or IP core. The testing means comprises a wrapper in which the core is embedded, this wrapper implements preferably the IEEE P1500 standard architecture but can also implement other standard architectures. The testing means can be extended to a Simple Network Management Protocol, SNMP, the widely adopted TCP/IP management protocol. The communication means comprises a test bus connected to the communication network. The proxy agent can implement the SNMP protocol, among others.
