Description
Technical field
The present invention relates to the D master-slave flip-flop of a kind of set structure and Scan Architecture, be particularly related to a kind of anti-single particle overturn (Single Event Upset, and the setable Scan Architecture d type flip flop of anti-single particle transient state (Single Event Transient, SET) SEU).
Background technology
In cosmic space, there are a large amount of high energy particles (proton, electronics, heavy ion etc.), sequence circuit in integrated circuit is subject to after these high-energy particle bombardments, the state of its maintenance likely overturns, this effect is called single-particle inversion effect, the LET(linear energy transfer of single-particle bombardment integrated circuit) value is higher, more easily produces single-particle inversion effect.Combinational circuit in integrated circuit is subject to after these high-energy particle bombardments, likely produce instantaneous electric pulse, this effect is called single-ion transient state effect, and the LET value of single-particle bombardment integrated circuit is higher, the instantaneous electric pulse duration producing is longer, and electric pulse is more easily gathered by sequence circuit.The upset if the state of sequence circuit makes a mistake, or single-ion transient state effect produce instantaneous electric pulse gathered by sequence circuit mistake, all can cause integrated circuit job insecurity even to produce fatal mistake, this is particularly serious in space flight, military field.Therefore, thus to integrated circuit reinforce reduce single-particle inversion effect and single-ion transient state effect more and more important.
D type flip flop is in integrated circuit, to use one of maximum timing unit, the anti-single particle overturn of the ability of its anti-single particle overturn and single-ion transient state to whole integrated circuit and the ability of single-ion transient state play a crucial role, and d type flip flop is carried out to corresponding reinforcing and can make the anti-single particle overturn of integrated circuit and single-ion transient state ability be improved.
Traditional d type flip flop is D master-slave flip-flop, generally forms by main latch with from level series of latches.Common lock storage is replaced with to DICE(Dual Interlocked Storage Cell, double interlocking memory cell) etc. redundancy ruggedized construction can realize primary particle inversion resistant d type flip flop.Transform on this basis input/output port, can realize anti-single particle overturn and single-ion transient state simultaneously.The people such as M.J.Myjak are at The47
ththe 47th IEEE Circuits and Systems Midwest international conference of IEEE International Midwest Symposium on Circuits and Systems() on " Enhanced Fault-Tolerant CMOS Memory Elements " (the strengthening fault-tolerant cmos memory cell) of delivering (2004, the I-453~I-456 page) on a kind of improved DICE circuit has been proposed, this circuit adopts DICE circuit to carry out anti-single particle overturn reinforcing, and bidirectional data line is divided into two write data lines and two read data lines, by the duplication redundancy of data wire, make at any time the single event transient pulse that propagates into DICE circuit by a certain data wire be difficult to cause the upset of whole circuit state, thereby realize the reinforcing for single-ion transient state.But there is positive feedback loop in the duplication redundancy of data wire, under compared with the single event transient pulse of long duration, can produce latch information upset, anti-single particle transient state ability is not high.
D.G.Mavis etc. are in the international Reliability Physics meeting of IEEE Reliability Physics Symposium() on time sampling d type flip flop circuit has been proposed in " Soft error rate mitigation techniques for modern microcircuits " (reducing the technology of modern microcircuit soft error rate) (2002 the 216th page-225 pages) of delivering.This circuit has been introduced delay and voting circuit in the feedback loop of latch data, thereby has possessed certain anti-single particle overturn and single-ion transient state ability.But voting circuit itself does not possess the ability of anti-single particle transient state, meeting output error data under single event transient pulse, anti-single particle transient state ability is not high.
Application number is the d type flip flop that 200910046337.5 Chinese patent discloses a kind of anti-single particle overturn and single event transient pulse.This invention is the d type flip flop that a kind of structure is similar to time sampling structure, comprises two variable connectors, two delay circuits, two shutter circuit and three inverters, has realized the reinforcing of anti-single particle overturn and the single-ion transient state of d type flip flop.This patent has the ability of anti-single particle transient state, but because the output Q of the 3rd reverser connects the input VIN0 of second variable connector, formed positive feedback loop, under compared with the single event transient pulse of long duration, can produce latch information upset, anti-single particle transient state ability is not high.
Common D master-slave flip-flop is unfavorable at test phase, circuit being detected, and makes test job become very loaded down with trivial details, complicated.On common D master-slave flip-flop architecture basics, add Scan Architecture, can effectively simplify circuit test work, can be by the input of sweep signal control D master-slave flip-flop at test phase, and then control circuit state.
Some integrated circuit needs the state of d type flip flop in control integration circuit, forces d type flip flop output low level and the data of wherein storage are set to logical one.On the original architecture basics of Scan Architecture d type flip flop, increase setting circuit and asserts signal input, can realize the set structure of d type flip flop, and control the set function of d type flip flop by asserts signal.But at present setable Scan Architecture d type flip flop anti-single particle overturn and anti-single particle transient state ability are not high, are unfavorable for using in the integrated circuit (IC) chip in the fields such as Aeronautics and Astronautics.
Application number is that 201110323794.1 Chinese patent discloses a kind of primary particle inversion resistant setable Scan Architecture d type flip flop, as shown in Figure 1, this invention is by clock circuit, main latch, form from latch, scan control buffer circuit, output buffer, can be under the single-particle bombardment compared with high LET value normal work and do not produce single-particle inversion.Because this invention does not adopt buffer circuit in clock circuit, before main latch, so do not possess the ability of anti-single particle transient state, and main latch, do not adopt duplication redundancy from latch, in the time that the LET value of single-particle bombardment is higher, the some node upsets on circuit can cause whole circuit to overturn.
