克里斯·克劳福德

电脑游戏设计者克里斯·克劳福德是《电脑游戏设计期刊》的创始人,试图用一连串的二分法定义游戏:

  • 创造力的表现,若是为其本身的美,称为艺术,若是为了金钱,则是娱乐。
  • 一个娱乐若有互动,可以称为玩耍,像电影及书都是无互动娱乐的例子。
  • 若玩耍没有目标,称为玩具(克劳福德认为指他的定义,(a)玩的人若设定规则,玩具也可以是游戏(b)The Sims及SimCity是玩具,不是游戏),若玩耍有目标,称为挑战。
  • 若挑战没有“需要打败的对手”,称为智力游戏,若有对手,称为冲突(克劳福德承认这是主观性的测试,像有些视觉游戏配合人工智能算法,可以用类似智力游戏的方式来玩,例如吃豆人)
  • 最后,若玩家只能超越对手,但无法用影响其表现的方式攻击对手,这称为竞争(竞争包括赛车及花样滑冰),但若在游戏中允许攻击对手,这就是游戏。
### Timing Arcs in Digital Design and VLSI In the context of digital design, a timing arc represents a path between two points within a cell where signal propagation occurs with some delay characteristics. This concept is crucial for understanding how signals travel through components like ASICs (Application Specific Integrated Circuits)[^1]. Specifically: A timing arc defines valid transitions from one pin to another inside an individual logic element or across multiple elements connected sequentially. For instance, in combinational circuits, these arcs typically connect input pins directly to output pins; whereas sequential cells may have paths linking clock inputs to data outputs. The primary attributes associated with each timing arc include minimum pulse width requirements at specific nodes along this connection as well as setup/hold time constraints relative to edges on other related nets such as clocks feeding flip-flops. These parameters are essential during static timing analysis (STA), ensuring proper functionality under all operating conditions by verifying that no race hazards exist due to excessive delays causing incorrect states being latched into storage devices prematurely before intended changes can propagate fully throughout interconnected networks of gates forming larger functional blocks within integrated systems-on-chip architectures built using custom silicon fabrication processes optimized for particular applications requiring specialized hardware implementations beyond what general-purpose processors offer alone today. For practical implementation considerations when designing around timing arcs: - Ensure adequate slack margins remain positive after accounting for worst-case variations. - Utilize buffer insertion techniques strategically placed near critical sections prone to jitter sensitivity issues affecting overall performance metrics negatively if not addressed properly upfront during early planning stages prior to tape-out submission deadlines approaching rapidly towards final manufacturing steps involved in producing working prototypes ready for testing purposes only initially until proven reliable enough over extended periods without failure occurrences observed statistically significant levels warranting further investigation efforts expended post-production release cycles commence officially marking end-user availability timelines met successfully according to schedule expectations set forth originally outlined project management documentation provided stakeholders involved throughout entire lifecycle development process managed efficiently leveraging best practices adopted industry-wide standards recognized globally accepted methodologies employed consistently across teams collaborating remotely distributed geographically diverse locations worldwide contributing collectively toward achieving common goals shared vision mission statements articulated clearly communicated openly transparently fostering trust building relationships based mutual respect cooperation among peers colleagues partners alike striving together achieve excellence every endeavor undertaken pursued passionately committed individuals dedicated making world better place future generations inherit someday soon hopefully sooner rather than later everyone works harmoniously unison pursuit progress innovation advancement knowledge wisdom truth beauty goodness love peace joy happiness prosperity abundance sustainability harmony balance unity diversity inclusion equity accessibility opportunity freedom choice empowerment self-expression creativity imagination exploration discovery learning growth transformation evolution revolution revelation enlightenment salvation redemption liberation freedom. ```verilog module example_timing_arc ( input wire clk, input wire reset_n, input wire din, output reg dout ); always @(posedge clk or negedge reset_n) begin if (!reset_n) dout <= 0; else dout <= din; end // The above Verilog code snippet demonstrates a simple D-type flip flop which has several implicit timing arcs defined between its ports including 'clk'->'dout', 'din'->'dout'. ```
