SUNNYVALE, Calif., April 20, 2005 — Synplicity Inc. (Nasdaq: SYNP), a leading supplier of software for the design and verification of semiconductors, today announced financial results for the quarter ended March 31, 2005. Revenue for the quarter ended March 31, 2005 was $14.6 million, an 8 percent increase from revenue of $ 13.5 million for the quarter ended March 31, 2004 and a 4 percent sequential decrease from revenue of $15.1 million for the quarter ended December 31, 2004.

On a generally accepted accounting principles (GAAP) basis, net income was $515,000, or $0.02 per diluted share, for the quarter ended March 31, 2005, which included amortization of intangible assets from acquisitions of $223,000 and stock-based compensation expense of $9,000. For the quarter ended March 31, 2004, GAAP net income was $296,000, or $0.01 per diluted share, which included amortization of intangible assets of $223,000 and stock-based compensation expense of $62,000. For the quarter ended December 31, 2004, GAAP net income was $803,000, or $0.03 per diluted share, which included amortization of intangible assets from acquisitions of $222,000 and stock-based compensation expense of $29,000.

Pro forma net income was $747,000, or $0.03 per diluted share, for the quarter ended March 31, 2005, compared to pro forma net income of $581,000, or $0.02 per diluted share, for the quarter ended March 31, 2004, and pro forma net income of $1.1 million, or $0.04 per diluted share, for the quarter ended December 31, 2004. Pro forma figures exclude the impact of amortization of intangible assets and stock-based compensation expense. A reconciliation of GAAP to pro forma net income is included with this press release.

“The momentum we felt in both our FPGA and ASIC business at the end of last year has continued into the first quarter of 2005,” said Gary Meyers, president and CEO. “During the first quarter of 2005 we grew product bookings, revenues and earnings over last year's first quarter, with solid execution across the product lines. We believe our focus on products for the FPGA and structured/platform ASIC markets will lead to continued growth this year,” Meyers concluded.

Use of Non-GAAP Financial Measures
This press release includes financial measures for net income and net income per share that exclude certain non-cash charges and that have not been calculated in accordance with GAAP. These measures differ from GAAP in that they exclude the amortization of intangible assets from acquisitions and stock-based compensation expense for stock options granted prior to Synplicity's initial public offering. Synplicity has previously provided these measurements in addition to GAAP financial results because it believes they provide a consistent basis for comparison between quarters that is not influenced by certain non-cash expenses and therefore are helpful to understanding Synplicity's underlying operational results. Further, these non-GAAP measures are some of the primary measures Synplicity's management uses for planning and forecasting. These measures should not be considered an alternative to GAAP, and these non-GAAP measures may not be comparable to information provided by other companies.
