transition diagram

Transition diagram（状态转移图）是一种用于描述系统状态和状态之间转移关系的图形化工具。它由有限状态机和状态图组成，可以清晰地表示出一个系统或者进程在不同的状态之间转移的过程，以及这些转移所需要满足的条件和产生的动作。在软件开发中，transition diagram可以用于分析和设计复杂的系统，并且在测试和调试过程中也有着重要的应用。

一个典型的transition diagram由若干状态和状态之间的转移箭头组成，每个状态表示系统或者进程在某个特定的时间点所处的状态，转移箭头表示从一个状态到另一个状态的条件和动作。通过对transition diagram的分析，可以清晰地了解系统在不同状态下的行为和响应，从而有效地优化系统设计和性能。

(Counter Design) Consider the design of a 4-bit Gray-code counter (that is, only one of the state bits changes for each transition) that counts in the following sequence: 00,0001,0011,0010,0110,01110101,0100,1100,1101,1111 11101010, 1011, 1001, 1000,and then back to 0000,00011 etc(a)Draw a state diagram and next-state table.

Here is the state diagram and next-state table for the 4-bit Gray-code counter:

Invalid transition. Invalid event: HOST_SVCCOMP_START at INIT

As an AI language model, I cannot provide a specific solution without more context. However, this error message typically occurs in software development when a state machine or finite state machine encounters an unexpected event. In this case, the "HOST_SVCCOMP_START" event is not a valid event for the "INIT" state.

To fix this error, you may need to review the state machine diagram and check if the event is allowed in the current state. Alternatively, you may need to modify the state machine to handle this event differently or add a new state to handle this event.
