After the synthesis code word of each state of signal is obtained, step S12 can be performed, i.e.,：It is connect by input and output
The synthesis code word of each state of the port transmission signal.
Wherein, " input/output interface " can be the interface for the various states that debugging signal is used for transmission on chip.Such as exist
It is illustrated in background technology, during integrated design circuit, it will usually reserved debugging function, thus can also remain in advance
The interface of the various states of transmission debugging signal.
" transmission " can refer to input, can also refer to output.That is, for example, each state for signal
Code word is synthesized, can chip interior be input to by input/output interface, so that the processing unit in chip is to the every of the signal
The synthesis code word of a state is decoded, and then determines each state of the signal；Another situation, can also be by chip
Processing unit adds the starting code word before the state encoding code word of each state of another signal, another to obtain this respectively
The synthesis code word of each state of one signal, finally by the input/output interface of chip by each state of another signal
Synthesis code word is output to chip exterior.No matter the processing unit in chip does which kind of above-mentioned processing, can pass through the defeated of chip

Optionally, it please refers to Fig.2, Fig. 2 is the method according to another transmission signal shown in an exemplary embodiment
Flow chart.As shown in Fig. 2, the method for another transmission signal that the disclosure provides is gone back in addition to including step S11 and step S12
Including：
Step S10：According to the most short duration of each state of the signal and/or each state of the signal it
Between the state encoding code word for redirecting relationship, determining each state of the signal.
Before being illustrated to step S10, first to " the most short duration of each state of signal " this noun into
Row explanation.
Above it is stated that for the signal with M state, each state can be denoted as V0、V1、V2、……
VM-1, wherein, m-th of state of the signal can be denoted as Vm, m is the integer more than or equal to 1 and less than or equal to M, then the signal
The length of the state encoding code word of each state can be denoted as W0、W1、W2、……WM-1, wherein, m-th of state of the signal
The length of state encoding code word can be denoted as Wm；The most short duration of each state of the signal can be denoted as T0、T1、
T2、……TM-1, wherein, the most short duration of m-th of state of the signal can be denoted as Tm。
Before the explanation of most short duration of a state is provided, the duration of a state is said first
It is bright.The duration of one state refers to：Being carved at the beginning of since the state, until knot of the state transition to another state
The beam moment stops, and the difference between start time and finish time is the duration of the state.The duration of one state,
It can be calculated according to the clock cycle of chip for unit, the duration of a state may be 2 clock cycle, can also energy
For 5 clock cycle.
The most short duration of one state refers to：Shortest duration in all durations of the state.Example
Ground, V0It may continue 2 clock cycle, it is also possible to continue 5 clock cycle, thus can determine V0It is most short when also continuing 2
Clock period, then T0Equal to 2 clock cycle.
Next, the relationship that redirects between each state of signal illustrates.In order to describe simplicity, parent status is proposed
With the concept of sub- state.State A jumps to state B namely state B comes from state A, thus, state A is father's shape of state B
State, and state B is the sub- state of state A.Same state may there are one or multiple parent status, same state may also there are one
Or multiple sub- states.What the parent status of one state may be to determine, it is also possible to random.The sub- state of one state may
One be to determine, it is also possible to which what is be to determine is multiple.Similarly, may be to determine one of the parent status of a state, it is also possible to
What is be to determine is multiple.
Illustratively, it please refers to Fig.3, Fig. 3 is the jump between each state according to the signal shown in an exemplary embodiment
The schematic diagram transferred the registration of Party membership, etc. from one unit to another.Signal shown in Fig. 3 has 9 states, is respectively：V0、V1、V2、V3、V4、V5、V6、V7、V8.Shown in Fig. 3
Signal each state between the relationship that redirects be：V0Jump to V1, V1Jump to V2、V3、V4, V2Jump to V5And V6, V5With
V6Jump to V8, V7Jump to V0, V1Jump to V8.Thus, V0Be to determine one of sub- state：V1。V1Sub- state be true
Fixed is multiple：V2、V3、V4, similarly, V2Sub- state be also to determine it is multiple：V5And V6。V1Be to determine one of parent status：
V0, V8Parent status be to determine it is multiple：V1、V5And V6。
If only there are one parent status, which can be represented a state with a state encoding code word；If one
A state has R parent status, then the state can be represented with R state encoding code word, a state encoding code word of the state
It is corresponding with a parent status of the state.Illustratively, relationship is redirected as shown in Figure 3, V1Parent status be to determine
One：V0, therefore, V0It can be represented with a state encoding code word；V8Parent status be three：V1、V5And V6, therefore, V8
It can be represented with three state encoding code words.
Next, step S10 is illustrated.
Wherein, "and/or" is a kind of incidence relation for describing affiliated partner, and expression may have three kinds of relationships, for example, A
And/or B, it can represent：Individualism A exists simultaneously A and B, these three situations of individualism B.
In order to transmit each state of signal by input/output interface few as possible and save transfer resource as possible,
Disclosure proposition can obtain the state encoding code of each state of signal according to one or both of two reference factors
Word, with the length of the state encoding code word of each state of compressed signal as possible namely：Compile the state of each state of signal
