Once you added your constraints, also do a SETUP> report net constraint to make sure that the constraint has been added. Answer (1 of 2): Contact means it is a connection to source , drain and poly, while via is used to make connection between 2 metal layers. The tool considers exclude pins only in calculation and optimizations for design rule constraints. After all the setup constraints and modeling directives are added, the tool must be toggled to LEC mode for mapping key points and comparison. PPT Testing in the Fourth Dimension - Auburn University Add comment. In addition, logic libraries can provide timing information for hard macros, such. The schematic from LEC debug tool printed out too many gates and connections. add examine point-all examine. Exclude pin: Exclude pin are clock tree endpoints that are excluded from clock tree timing calculation and optimization. Activity points.

Constrain internal nets, such as primary input, primary output, and tied . Tried set flatten model -seq_constant, remodel -seq_constant -repeat but it seems to be increasing my non-eq points instead of resolving them. To do this, use add pin constraints and add ignore outputs commands. add pin constraint 0 scan\_en -revised add instance constraint 0 U1 -revised. We are offering a diverse and inclusive space where all should feel valued, regardless of their gender, race, ethnicity . define_dft shift_enable -name scan_enable -active high SCAN_EN_IN => SCAN_EN_IN is defined as shift_enable and referred to as "scan_enable". add pin constraint 0 scan_enable-revised. Appropriate constraints depend on the element types you are using.

Usually, you do not have to add anymore Conformal LEC constraints to verify your netlists. 4. These constraints re°ect the needs that the design must meet. 6. [-root pin_name ] [-routing_rule rule_name] [-use_default_routing_for_sinks ] The nondefault routing rules of clock shielding apply only to nets that are assigned with nondefault routing rules. SDC is a short form of "Synopsys Design Constraint". The simplest design latch and flip-flop both are having 3 pins, One input data pin (D), one input clock/enable pin (CP/E) and, one output pin (Q). For the execution of LEC, the Conformal tool requires three types of files. 002157664 Genus equivalent for TCL vars: CCR 2073825. 保留结果的session文件.

Explain about the LEC procedure and issues faced and solved with respect to non-equivalent points. add pin equivalence CLK -invert CLK\_n -revised. However, you can manually add or delete compare points for LEC on your purpose. Class Assignment: Projected Student Conflicts add pin constraint 0 scan_enable_i -both add pin constraint 0 scan_mode_i -both Set flatten Model : Usually synthesis does lots of optimization. ; Wait for 1000 milliseconds, â ¦ The design example discussed in this white paper is from a real world debugging session by a GOF customer. Draw the free body diagram for the truss. Resource constraints of mobile devices . regards, Masood PS: You realize, by adding the one_hot constraint you are just telling Conformal-LEC to ignore the non-one-hot conditions.

In that case lec may never catch this bug if we don't check for this constraint (se=1, sm=0). Map the Points and Compare. You can specify these constraints based on the utilization, aspect ratio, and dimensions of the die. add pin constraint 0 scan_enable-revised 4/7 Figure 4 This is how golden DFF vs. revised DFF looks after scan insertion. read design compare Some commands are legal only under certain circumstance e.g. The datamemory is instantiated with one spram library memory module..I add notranslate to spram and still I got 1 non equivalent black box after comparison..Still that datamemory is the blackbox and 1 input pin of it shows mismatch.Can you please be more specific?Since Im a fresher I face some problem to debugg this Draw the free body diagram for the truss a is a pin and b is a rocker. SETUP > add black box U2 -model -golden // U2 모듈을 blackbox 로 봅니다. add pin constraints 0 scan_en_in -revised => to force scan_en_in to 0 for gate netlist (since scan_en_in not tied to anything in golden RTL). The input signal can be defined on a top-level port or an internal driving pin. After all of the setup constraints and modeling directives are added, the device should be toggled to LEC mode for mapping key factors and comparability.

Via in any of the integrated circuit , via is used to connect a metal trace of 1 metal layer with metal stack of another layer. . This time the Revised Design has been created by changing some Constarints in DC. You can indicate whether to add shielding to leaf pins by using the-use_default_routing_for_sinks option. Appropriate constraints depend on the element types you are using. XGrid slots: none, ie, no placement grid, no "1 gate in 1 slot" constraints X Pins: must be fixed somewhere around boundary of the chip X Wires: we only allow 2-point connections; we minimize Σ length 2 For example minimum area, minimum speed and maximum power dissipation. add net constraints one\_hot my\_out -revised.

New pin-swap groups are automatically named using numerical values (e.g., 1, 2, 3, etc.). Specify behavior, such as one-hot or one-cold. After all of the setup constraints and modeling directives are added, the device should be toggled to LEC mode for mapping key factors and comparability. 形式验证LEC的流程 . where 1 pin is PI and other pin is sm). Set scan constraints: If the netlist is a scan inserted, RTL vs Netlist comparison has to be done by disabling scan path. This section describes the details of the Conformal LEC commands in the scripts to help you compare the revised netlist with the golden netlist.

Before, only constraints between Lec 1 - Lec 1a - Lab 1 and Lab 1 - Lab 1a - Lec 1 were created, allowing Lec 1a to overlap with Lab 1a. Normally solid modeling and automatic meshing is NOT useful for line element models. −Add extra bits in the cache to predict the way of the next cache access pBlock predictor bits −Multiplexor is set early to select the desired block pAnd in that clock cycle, only a single tag comparison is performed in parallel with reading the cache data −A miss results in checking the other blocks for matches in the next clock cycle Mapping process It's done by using the following command: set system mode lec. 需要比对的两个文件，一个是标准的golden,一个是待比对的revised。 各种库文件的verilog model.
