| Pay vs Performance [Table Text Block] | PAY VERSUS PERFORMANCE As highlighted in “Compensation Discussion and Analysis,” one of the primary principles of our compensation program is to ensure t at-risk For our executives, over 75% of their opportunity is tied to long-term equity incentives which will depend on our stock price performance while roughly 10% to 15% of our executive pay is tied to annual financial and operational performance. As a result, we would expect that our Compensation Actually Paid in the table below will have a stronger correlation with our TSR and stock price performance than our annual financial and operational performance. We expect a strong correlation to stock price performance through the combination of (a) having a significant portion of executive pay tied to long-term incentives (“LTI”) and (b) using options as part of our annual LTI mix (50% for our CEO and 34% for our other NEOs) and periodic LTP awards that require meeting material stock price growth hurdles before any value is delivered to our executives. Despite continued strong business performance (including increased revenues, operating margin, and net income) the Cadence’s stock price declined by 14% in 2022 driven by broader market fears of a recession and uncertainty around geopolitical issues. In the charts and descriptions of the relationships presented below we note that (a) we show two Principal Executive Officers (“PEOs”) over the three-year period due to our CEO transition in 2021 (Dr. Devgan is PEO #1 for 2022 and 2021 and Mr. Tan is PEO #2 for 2021 and 2020) and (b) there is a notable difference in the Compensation Actually Paid for 2020 compared to 2021 despite continued stock price performance in 2021. The higher Compensation Actually Paid values for 2020 when compared to 2021 reflect three primary factors: (a) the Compensation Actually Paid calculation measures the change in fair value of equity awards (not the absolute value), (b) our stock price grew 97% in 2020 compared to a 37% increase in 2021 indicating that the change in the fair value of equity awards would be larger in 2020 compared to 2021, and (c) we had five LTP tranches as part of the 2020 calculation (two outstanding LTP I awards and three outstanding LTP III awards) compared to four LTP tranches as part of the 2021 calculation (one outstanding LTP I award and three outstanding LTP III awards).
