Good 401k match, good amount of PTO's.
The benefits package I would consider comparable to Xilinx' competitors. No pension but 401k with a company match component. Meaningful bonus/stock compensation.
best thing is the comprehensive converage and stock option plans
The benefits are good but not as rich in areas like vision, dental or life insurance as other companies I've worked for. For example the life insurance and supplemental life available may take care of the funeral but certainly won't do more than that. Previous companies I've worked for allowed for up to 5x or 7x the employee salary and up to 250,000 for a spouse. If you are just looking for the basics they have it.
