Mounting PLD densities expand your ASIC options
All things being equal, designers prefer field-programmable ICs to mask-customized chips--that is, traditional gate arrays and standard cells. With field-programmable chips, circuits are more quickly, simply, and inexpensively customized.
The problem with using such parts, though, is that too little has been equal.
Although field-programmable ICs--which include PLDs, PALs, EPLDs, EEPLDs, and field-programmable gate arrays (FPGAs)--let designers customize circuits quickly, simply, and inexpensively, field-programmable interconnects are larger and slower than mask-customized ones. Consequently, the ...
