Business Combinations [Abstract]
Business Combination	Business Combination During the six months ended April 30, 2023, we completed one acquisition for aggregate purchase consideration of $38.6 million, net of cash acquired. The purchase consideration was allocated as follows: $20.3 million to identifiable intangible assets and $23.0 million to goodwill. The total purchase consideration is preliminary, and as additional information becomes available, we may further revise it during the remainder of the measurement period, which will not exceed 12 months from the closing of the acquisition. The goodwill recognized was assigned to the Design Automation reporting unit, and was not deductible for income tax purposes. We have included the financial results of this acquisition in our condensed consolidated financial statements from the date of acquisition. These results were not material to our condensed consolidated financial statements. Transaction costs were $2.7 million and $5.3 million during the three and six months ended April 30, 2023, respectively. Transaction costs were $4.0 million and $6.1 million during the three and six months ended April 30, 2022, respectively. These costs mainly consisted of professional fees and administrative costs and were expensed as incurred in our condensed consolidated statements of income.
