Synopsys ( SNPS), a producer of integrated circuit design software, reported solid second-quarter results after the close of trading Wednesday, sending the company's shares higher in extended-hours action.

For the second quarter, Synopsys reported revenue of $292 million, a 57% increase over a top line of $185.6 million in the same period a year ago. Net income totaled $22.3 million, or 29 cents a share, compared with a profit of $21.4 million, or 33 cents a share, in the year-ago quarter.

Earnings before goodwill reached $61.2 million, or 80 cents a share, up from $25.1 million, or 39 cents a share, last year. On that basis, the company beat analysts' expectations. Thomson First Call carried a consensus estimate of 70 cents a share for the second quarter.

The difference between earnings before goodwill and GAAP earnings was primarily related to charges from the company's acquisition of Numerical Technologies, which was completed during the quarter, and the amortization of intangibles from prior acquisitions.

For the third quarter, Synopsys projected revenue of $288 million to $303 million and earnings before goodwill of 77 cents to 82 cents a share. For the fiscal year, Synopsys forecast revenue of $1.13 billion and $1.18 billion and earnings before goodwill of $2.95 to $3.10 a share. Analysts expect earnings before goodwill of 75 cents in the third quarter and $3.03 for the year.

After the close, shares of Synopsys were rising $2.41, or 4.7%, to $53.25 on Instinet.
