That article was written by some one who knows little about EDA. SYNP should have not have continued as an independent company for years. But Ken Mc and co. control the firm and did not want to give up till going alone did not make any sense any more (after the structured ASIC market never panned out). SNPS, if they integrate the right parts, can benefit from this; especially in the area of system level design including hardware/software together. That area can be a new growth area of EDA and standardization there can really help develop the market.
The "new" companies listed in the Fool article don't make sense-
Xilinx and Lattice Semi sell FPGAs, and their EDA tool acquisition would not be in the sweet-spot of Synopsys logic design tools.
LSI Corp. currently uses the Synopsys VCS simulator, plus multiple other Synopsys products. I don't know what he's talking about.
Avnet and Arrow Electronics are component distributors, and don't design chips. They do sell FPGAs and possibly resell the Synpicity products? I don't know.
Synopsys bought them I believe
1. to eliminate a logic synthesis competitor, and to gain their design team for other Synopsys products.
2. to get into the FPGA market so they have both IC design and FPGA products, to be able to negotiate single-supplier deals and discounts with customers.
3. to get prototyping and acceleration hardware from the DINI acquisition that Synplicity made, to compete more effectively against Cadence and Mentor Graphics, who have successful hardware divisions and products.
I believe that it was HAPS, not Dini that Synplicity bought. Synopsys had testimonials about Synplicity and Haps prior to the buy out. I believe Synopsys bought Synplicity to better compete against Cadence in the hardware acceleration arena IMHO. Synopsys had/has FPGA Express and had pretty good penetration several years back but I heard they were unwilling to make it best in class so I do not believe Synopsys is very interested in FPGA synthesis. Perhaps there may be marketing synergies with the combination.
