Embodiment 1

[0027] Such as figure 1 As shown, the present invention provides an FPGA1 (English abbreviation for Field Programmable Gate Array) with an embedded logic analysis function. The FPGA1 can help technicians to detect the signal of the FPGA1 when it is working, so as to debug and modify the FPGA1. Said FPGA1 includes at least one working module 13, said working module 13 is used to perform digital calculation or logic processing according to design requirements, which includes but not limited to: logic circuit, arithmetic circuit, input and output circuit and so on. The working modules 13 are connected by internal wires, and the working module 13 can also be connected to the pins of the FPGA1 so as to communicate with circuits / devices outside the FPGA1 through the pins. Each working module 13 can input / output one or more signals according to design requirements. Said FPGA1 also includes: a storage module 14 , a logic analysis module 12 and an interface module 11 .

Abstract

The invention provides an FPGA with an embedded logical analysis function and a logical analysis system. The FPGA comprises a working module, a storing module embedded in the FPGA, a logical analysis module and an interface module. The logical analysis module connected with the working module and the storing module is used for collecting signals input by the corresponding working module of FPGA based on received collecting commands, storing the collected signals in the storing module and outputting signals stored in the storing module when the collection is finished. The interface module connected with outer devices and the logical analysis module is used for performing protocol encapsulation / parsing processing on data transmitting between the logical analysis module and the outer devices. The data comprises collecting commands input into the interface module by the outer devices and signals input into the interface module by the logical analysis module. The logical analysis system comprises the FPGA and the outer devices connected with the FPGA.

Description

technical field [0001] The invention relates to an FPGA with embedded logic analysis function and a logic analysis system. Background technique [0002] At present, the field programmable gate array (Field Programmable Gate Array, referred to as FPGA), completes the circuit design with the hardware description language (Verilog or VHDL), and can be quickly burned to the FPGA for testing after simple synthesis and layout. The mainstream technology of modern IC design verification. These editable components can be used to implement some basic logic gates (such as AND, OR, XOR, NOT) or more complex combination functions, such as decoders or mathematical equations. In most FPGAs, these editable elements also contain memory elements such as flip-flops (Flip-flop) or other more complete memory blocks. System designers can connect the logic blocks inside the FPGA through editable connections according to design needs, just like a circuit board is placed in a chip. The logic bloc...
