| 1. A device for debugging an electronic circuit manufactured from an initial program in hardware description language, HDL,
comprising:
an instrumentation unit capable of
receiving the initial program;
receiving an additional program describing determined functions;
determining an additional circuit to be incorporated into the electronic circuit from said additional program, said additional
circuit comprising at least one input terminal and/or one output terminal connected to the electronic circuit and being capable
of setting to a determined value a signal selected from among a signal received at said input terminal, a signal provided
at said output terminal, or a signal internal to said additional circuit; and
providing a modified program in HDL language from the initial program incorporating a description in HDL language of the additional
circuit; and
a debugging unit capable of debugging a modified electronic circuit formed from the modified program, the debugging unit being
capable of communicating with the additional circuit to control the setting to said determined value of said selected signal.
