Cinnamomum cassia component called coumarin, which could damage the liver if consumed in larger amounts, European health agencies have warned against consuming high amounts of cassia. Other bioactive compounds found in the bark, powder and essential oils of "C. cassia" are cinnamaldehyde and styrene. In high doses these substances can also be toxic for humans. Cinnamomum cassia Cinnamomum cassia, called Chinese cassia or Chinese cinnamon, is an evergreen tree originating in southern China, and widely cultivated there and elsewhere in southern and eastern Asia (India, Indonesia, Laos, Malaysia, Taiwan, Thailand, and Vietnam). It is one of several species of "Cinnamomum" used primarily
SPICE and CIDER have been integrated into open source ngspice. The integrated circuit industry adopted SPICE quickly, and until commercial versions became well developed many IC design houses had proprietary versions of SPICE. Today a few IC manufacturers, typically the larger companies, have groups continuing to develop SPICE-based circuit simulation programs. Among these are ADICE at Analog Devices, LTspice at Linear Technology (available to the public as freeware), Mica at Freescale Semiconductor and TINA at Texas Instruments. Similarly to Linear Technology, Texas Instruments makes available a freeware Windows version of the TINA software (called TINA-TI), which also includes their version of
